Multi-encoder side-by-side, visual diff slider, batch zip, no 20/mo cap.
Drop images here
or click to choose, paste from clipboard. JPEG, PNG, WebP, AVIF, GIF.
Drop unlimited images. We compress with JPEG, WebP, and AVIF in parallel, pick the smallest, and let you verify pixel-by-pixel with a built-in diff slider. Batch-zip download. Your images never leave the tab.
Drop any number of images, paste a screenshot, or click to select. JPEG, PNG, WebP, AVIF, GIF accepted.
We compress with JPEG, WebP, and AVIF in parallel and pick the smallest. You can also force one format if you have legacy browser concerns.
One image, hit download. Many images, get them all in a single zip with one click.
Compress with JPEG, WebP, and AVIF (when supported) at the same time. See file size + visual quality for each. Pick the winner manually or trust the auto-pick. Squoosh shows one format at a time. We show all four in one row.
Drag a clip-path slider to compare original vs compressed pixel-by-pixel. Spot lossy artifacts before you ship. No free competitor (TinyPNG, iLoveIMG, Optimizilla) ships an in-place pixel diff.
Drop dozens of images at once. Each is compressed in parallel. Click 'Download all as zip' for one file with every compressed image. TinyPNG caps free use at 20 images per month. We have no limit.
Set Max dimension to the longest side. The tool scales by aspect ratio so you don't have to compute width and height. Resizing 4K images down to 1920 typically saves 80 percent before any encoder runs.
Canvas-based re-encoding strips all metadata. EXIF, GPS coordinates, ICC profiles, camera info: all gone. Critical for privacy when posting personal photos.
JPG to PNG, PNG to WebP, WebP to AVIF, all combinations. Pick the format that fits your use case (transparency, animation, modern compression) without leaving the page.
Drag from 10 to 100. The candidate cards re-encode on every change so you can hunt the optimal quality / size tradeoff in real time.
Native canvas encoders. No upload, no server, no log. Your images never leave the tab. Works offline after first page load.
Other 'free' compressors quietly upload your image to their server, run lossy encoding there, and keep a copy. Ours doesn't, because it can't. The tool is a bundle of JavaScript and the canvas API, that's it. Open the network tab, you'll see no requests.
Process unlimited images at any size. TinyPNG: 20 images per month, 5 MB max. Compressor.io: ad-supported with batch limits. iLoveIMG: 30 images max per batch. Ours: as many as your browser can hold.
Most tools force you to pick a format up front. Our Auto mode encodes with three encoders at the same time and picks the smallest result that meets your quality. Saves 10-30 percent over a fixed-format pick on most photos.
The diff slider lets you confirm there's no perceptible loss before you ship. No more 'looks fine in the thumbnail, breaks at full size' surprises after publishing.

Drop the hero + inline images, set max dimension to 1600, get them all back in a zip. Page weight drops, Core Web Vitals improve.
1200 by 630 sized OG images for social shares. Auto-pick decides between JPEG and WebP. Drag the diff to confirm no banding.
Paste a screenshot from clipboard, compress to under 200 KB, drop into a Slack message or GitHub issue. No upload to a third-party screenshot service.
Trip photos contain GPS coordinates by default. EXIF strip is on by default here. Photos are clean to publish without revealing where they were taken.
PNG to WebP for the modern web, JPG to AVIF for max savings, WebP to PNG for legacy compatibility. All in the same tool.
Some clients still cap attachments at 25 MB. Drop a folder of photos, compress to 60 percent quality, get a zip under the limit.
The tool uses native canvas encoders that ship with every modern browser. The image is loaded into a tab-local canvas, re-encoded, and delivered back to you. No upload. No server. No log. Open your browser's network tab and you'll see zero outbound requests.
EXIF, GPS coordinates, ICC color profiles, and other private metadata are stripped by default during re-encoding. Critical when uploading personal photos to a CMS or sharing screenshots that might contain sensitive context. Toggle the strip off if you specifically want to keep camera info.
Optimize hero images, OG cards, and inline content. Auto-pick the format your CDN should serve. Work in batches with the zip download.
Strip EXIF + GPS before publishing. Use the diff slider to check that artistic detail survives the compression.
Paste a screenshot from clipboard, compress, drop into Slack or a GitHub issue. No third-party screenshot service in the loop.
If you wouldn't send your photo to a stranger's server, don't use a competitor that runs compression server-side. We don't have a server.
Free. No signup. No 20-per-month cap. Drop a batch and download as zip.
