Compress JPG, PNG, WebP and GIF images up to 80% smaller without visible quality loss. Batch compression runs in your browser — no upload, no signup.
The Image Compressor shrinks JPG, PNG, WebP and GIF files directly in your browser, cutting file size by up to 80% without visible quality loss. Instead of uploading photos to a server and waiting for a queue, the compression runs on your own device using the browser's canvas and codec APIs, so large batches finish in seconds and nothing you upload is ever transmitted anywhere.
It suits anyone who needs smaller images fast: bloggers trying to hit a page-speed score, sellers uploading product photos with strict size limits, or people who just need to compress a photo to under 100KB or 50KB for a form. A live before-and-after preview and file-size readout let you dial in the quality slider until the image is as small as possible while still looking sharp on screen.
The estimated output size updates as you move the quality slider, so you can target an exact limit such as 100KB or 50KB without guessing. This removes the trial-and-error of re-exporting from desktop software.
Multiple images can be compressed together with the same settings, which is much faster than opening files one at a time in an editor. A ZIP download bundles the results for easy uploading elsewhere.
Compression happens using in-browser canvas rendering, so photos never leave your device. This matters for client work, ID scans or anything you would rather not send to a third-party server.
JPG or WebP gives the smallest files for photographs because they use lossy compression tuned for natural colour gradients. PNG keeps flat-colour graphics like logos and screenshots crisp but produces larger files, so WebP is often the better choice when the target platform supports it. GIF should generally be converted to PNG or WebP unless animation is required.
Most photographs can be compressed to a quality setting of 70–80% with no visible difference on a typical screen, cutting file size by 60–80%. Below about 50% quality, blocky artefacts start appearing around sharp edges and text. The live preview lets you find that threshold visually rather than relying on a fixed number.
Desktop tools like Photoshop's export dialog or standalone compression apps require installation and manual file handling. This tool needs nothing installed, processes a whole batch in one pass, and keeps files private since nothing is uploaded — a practical advantage when compressing sensitive documents or client photos.
Most photos shrink by 60–80% at a quality setting of 70–80 with no visible difference on screen. Use the live preview and the before/after size readout to pick the smallest file that still looks sharp.
JPG/JPEG, PNG, WebP and GIF are supported. For photographs JPG or WebP gives the smallest files; for logos and screenshots with flat colour, PNG or WebP keeps edges crisp.
