How do I compress an image without uploading it?

Open Image Studio and drop the image onto the canvas, or click Open. Pick Compress from the toolbar, choose a quality slider value (0-100) and an output format (JPG, WebP, AVIF), and click Save. The compression runs in the browser via wasm-vips — your image is never sent to a server. Most photos drop 50-80 % in size at quality 80 with no visible loss.

How do I resize an image online?

Open the image and pick Resize from the toolbar. Enter a target width and height in pixels, set the resampling algorithm (Lanczos for high quality, bicubic for speed), and choose whether to preserve aspect ratio. Hit Save to download. Aspect-ratio presets for Instagram (1080×1080), TikTok (1080×1920), YouTube thumbnail (1280×720), and A4 print are coming. Everything runs locally; even a 50 MP photo stays in your browser.

How do I convert image formats (JPG, PNG, WebP, AVIF)?

Open the image and pick Convert from the toolbar. Choose the target format — JPG (smaller, lossy), PNG (lossless, transparency), WebP (modern, both modes), or AVIF (smallest at high quality). Set the quality slider for lossy formats. The conversion uses wasm-vips and Squoosh codecs, so output quality matches the best desktop tools. Original files are never uploaded.

How do I rotate an image online?

Open the image and pick Rotate from the toolbar. Click the 90° clockwise, 90° counter-clockwise, or 180° buttons, or drag the rotation handle for arbitrary angles. EXIF orientation tags are normalized so the rotation is correct in every viewer. Save the result as JPG, PNG, or WebP.

How do I crop an image online?

Open the image and pick Crop from the toolbar. Drag the selection handles on the canvas, type exact pixel coordinates, or pick an aspect ratio (1:1, 4:5, 4:3, 16:9, 9:16) for a constrained crop. The preview updates live. Aspect-ratio presets for social media (Instagram 1:1, TikTok 9:16, YouTube 16:9) are on the roadmap. Save the cropped image at your chosen format and quality.

How do I add a watermark to an image?

Open the image and pick Watermark from the toolbar. Choose text or image; for text, enter the string and pick a font, size, color, opacity, rotation, and tile mode (single, repeated diagonally, or anchored to a corner). For images, drop a PNG or JPG and choose its position and opacity. The watermark is rendered into the saved image — visible everywhere it's viewed.

How do filters work in Image Studio?

Open an image and pick Filters from the toolbar. Choose from a curated set — black and white, sepia, vintage, blur, sharpen, vignette, and more — with intensity sliders for each. The preview updates in real time so you can dial in the look. Filters are GPU-accelerated where the browser supports it, so even 4K photos respond instantly.

How do I adjust image color (brightness, contrast, saturation)?

Open the image and pick Color Adjust from the toolbar. Sliders for brightness, contrast, saturation, hue, exposure, and gamma update the canvas live. Reset any slider with a double-click. Save the adjusted image as JPG, PNG, WebP, or AVIF. All processing runs in the browser via wasm-vips — no upload.

How do I add text to an image?

Open the image and pick Add Text from the toolbar. Click anywhere on the canvas to drop a text layer, type your message, then style it — font family, size, weight, color, stroke, shadow, opacity. Drag layers to reposition. Add multiple text blocks for memes, captions, or annotations. Save the composited image.

How do I compress multiple images at once?

Pick Bulk Compress from the toolbar and drop a folder or multi-select files. Pick a target quality, format, and resize policy (e.g., max 1920 px on longest side). Image Studio compresses every file in parallel via Web Workers and packages the results as a ZIP. Useful for prepping a photo gallery for the web, shrinking a batch of screenshots, or converting an album to WebP. Everything stays local.

Is my image uploaded to a server?

No. Image Studio runs every tool — compress, resize, convert, rotate, crop, watermark, filters, color adjust, add text, bulk compress — entirely in your browser using WebAssembly (wasm-vips, Squoosh codecs, Canvas APIs). Your image is loaded into memory once, processed locally, and saved back to your disk. No upload, no temporary cloud copy, no telemetry. You can verify in DevTools → Network: the only requests are the WASM binaries themselves, cached after first use.

What's the maximum image size I can edit?

Image Studio handles files up to 100 MB and resolutions up to 24,000 × 24,000 pixels on a modern laptop. Phones may struggle above 50 MB or above 8000 px due to memory limits — the browser will OOM-crash if it can't hold the decoded bitmap. For most photos, including 50 MP DSLR raws and 4K screenshots, performance is instant.

Does Image Studio preserve EXIF metadata?

By default, Image Studio strips EXIF on export — this protects your privacy by removing GPS coordinates, camera serial numbers, and timestamps. A toggle to preserve EXIF will be added; ask if you need it. Color profiles (sRGB, Display P3, Adobe RGB) are preserved automatically so the output looks the same as the input on calibrated displays.

Can I edit transparent PNGs and animated GIFs?

Yes. PNG transparency is preserved through every operation that supports it (resize, crop, rotate, watermark, filters). Animated GIFs are loaded as the first frame in most tools; full multi-frame GIF editing is on the roadmap. WebP supports both transparency and animation; Image Studio decodes both modes.

What image formats does Image Studio support?

Input: JPG/JPEG, PNG, WebP, AVIF, GIF, BMP, and TIFF (most variants). Output: JPG, PNG, WebP, and AVIF with quality control. HEIC input support is on the roadmap (separate dedicated converter at /convert/heic-to-jpg). Vector formats (SVG) are handled by the SVG-to-PNG converter at /convert/svg-to-png.

Why does AVIF give the smallest files?

AVIF is a modern codec based on AV1 that compresses about 30-50 % better than WebP and 50-80 % better than JPG at equivalent visual quality. It supports 12-bit color, HDR, and transparency. Trade-off: encoding is slower than JPG/WebP (a few seconds per high-resolution image versus instant), and AVIF is supported by Chrome, Firefox, Safari, and Edge — but a small set of older browsers and image viewers cannot read it.

Does Image Studio work offline?

Once the page has loaded and the wasm-vips and Squoosh codec binaries are cached (after one online use), Image Studio works offline for compress, resize, convert, rotate, crop, watermark, filters, color adjust, and add text. The first visit needs network to fetch the WASM binaries; after that, you can edit images on a plane, in a tunnel, or behind a firewall.

What happens to my image after I close the tab?

It's gone. Image Studio holds your image only in browser memory while the tab is open. There is no IndexedDB persistence, no LocalStorage of bitmap data, no service-worker copy of the file, no analytics event with the image payload. Closing the tab releases the memory and the image is irrecoverable from Image Studio. The same model as a desktop editor that doesn't save automatically.

Can I use Image Studio on mobile?

Yes. Image Studio works in mobile Chrome, Safari, Firefox, and Edge on Android and iOS. The toolbar adapts to the smaller screen and the canvas supports pinch-zoom, pan, and touch crop handles. Memory is the main constraint — phones can run out of RAM on very large RAW or panoramic images. For everyday photos and screenshots, mobile works just as well as desktop.

How does Image Studio compare to TinyPNG or iLoveIMG?

TinyPNG and iLoveIMG upload your image to their servers and apply compression there, which means daily upload caps, file-count limits, and trust assumptions about what they do with your data. Image Studio runs every operation in the browser via WebAssembly — no upload, no account, no daily caps. The tradeoffs: TinyPNG has highly tuned proprietary models that occasionally beat raw codec output; we trade that for full privacy and unlimited use.

Does Image Studio leave any trace on my computer?

Only the cached WebAssembly binaries (wasm-vips, codecs) and your browser's normal cache (favicons, fonts, page itself). The image you edit is held in RAM and discarded when you close the tab. No file is written to disk other than what you explicitly download via Save. In Incognito/Private mode, even the WASM cache is cleared on tab close.

Can I batch-rename files when bulk-compressing?

Bulk Compress preserves the original filename and appends a suffix like "-compressed.jpg" by default. A custom rename pattern (e.g., "img-{n}.webp" for sequential numbering) is on the roadmap. The output ZIP is named after the source folder. Original files on disk are never modified — the ZIP is a separate download.

What's the difference between resize and crop?

Resize changes the dimensions of the entire image — nothing is removed, but the visual content is scaled smaller or larger. Crop removes pixels from the edges to extract a region — nothing is scaled, but pixels outside the crop area are discarded. Use Resize when you need a specific output size; use Crop when you want to focus on part of the image, change aspect ratio, or remove unwanted edges.

Why are my JPGs getting blurry after editing?

JPG is a lossy format — every save discards a bit of detail. Repeated open-edit-save cycles compound the loss. To avoid this: keep the original PNG or RAW around as a master, do all your edits in one session, and export to JPG only as the final step. Or use PNG, WebP-lossless, or AVIF-lossless as intermediate formats. Image Studio's quality slider lets you choose how aggressive the JPG compression is — 90+ usually preserves the image well.

Does Image Studio support color profiles like Display P3?

Yes. ICC color profiles (sRGB, Display P3, Adobe RGB, ProPhoto RGB) are read from the input and preserved through every operation. The export keeps the embedded profile so the image looks identical on calibrated displays. If your photo was shot in P3 by a recent iPhone or Mac and you don't want the wider gamut on a non-P3 device, the convert tool can normalize to sRGB.

Can I undo edits in Image Studio?

Yes. Every operation in the canvas — resize, crop, rotate, watermark, filter, color adjust, add text — pushes onto an undo stack. Press Ctrl/Cmd+Z to undo, Ctrl/Cmd+Shift+Z to redo. The history is per-image and lasts as long as the canvas tab is open. Closing the tab discards the history.

How does bulk compress handle different image sizes?

Each image in the batch is processed independently with the same target settings — quality, format, and optional max-dimension cap. So a 4K and a 720p image will both get re-encoded to your chosen quality, but only the 4K will be downscaled if a max-dimension cap is set. This is the right default for web use cases (gallery, blog hero images, social posts).

Can I use Image Studio in my company's secure environment?

Yes — that's exactly the use case. Because nothing is uploaded, the image never crosses your firewall and you don't need to vet a third-party data processor for GDPR, HIPAA, or internal compliance. The site loads over HTTPS and the WASM binaries are versioned and cached. A blocklist for cloud upload tools doesn't block Image Studio because there's nothing to upload.

Why does the first image operation take a few seconds?

The first time you use Image Studio, the wasm-vips binary (~2 MB) and the format-specific codec WASM (~500 KB-2 MB each) are downloaded. After that, the binaries are cached and every subsequent operation starts instantly. We split the codecs by format so you only pay the load cost for the formats you use.

What features does Image Studio not yet have?

On the roadmap and not yet shipped: HEIC input support (separate /convert/heic-to-jpg page is coming), AI background removal, AI upscaling (2x / 4x), social-media aspect-ratio presets, custom rename patterns for bulk compress, EXIF preservation toggle, and animated GIF / WebP multi-frame editing. Open a GitHub issue if any of these block your workflow.

Image Studio Online Free - Edit images with all tools in one place

How It Works

Open or Drop

Drop an image (or several) onto the canvas, or click Open to load files from your computer. Image Studio accepts JPG, PNG, WebP, AVIF, and GIF up to 100 MB. Everything is loaded in the browser via WebAssembly — your files never touch a server.

Pick a Tool

Use the toolbar to compress, resize, convert formats, rotate, crop, watermark, apply filters, adjust color, add text, or batch-compress multiple files. Each tool exposes the controls it needs and a live preview so you can see the result before you commit.

Edit and Preview

Chain multiple operations on the same image — crop, then resize, then add a watermark, then export. Undo and redo every step. The canvas updates in real time so you see exactly what will be saved.

Save

Download the result as JPG, PNG, WebP, or AVIF at the quality you choose. The browser prompts for a filename. Your originals stay untouched on disk; the edited copy is yours to keep.
