Our compressor uses the HTML5 Canvas API to re-encode your images at a specified quality level — entirely in your browser. No files are ever uploaded to any server. Everything is 100% private and instant.

We support JPG/JPEG, PNG, and WebP for both input and output. You can even convert formats — for example, upload a PNG and download it as WebP for much smaller file sizes.

At 75-85% quality, most images look virtually identical to the original but are significantly smaller. Use the before/after comparison to judge for yourself. For logos and graphics, use PNG format with higher quality settings.

Free users can compress images up to 10MB each. Pro users get up to 50MB per image. Since all processing is done in your browser, very large images may take a few seconds depending on your device speed.

Absolutely yes! All compression happens locally in your browser using JavaScript. Your images are never sent to any server, never stored, and never seen by anyone. Close the tab and everything is gone permanently.

WebP generally gives the best results — typically 25-35% smaller than JPG at the same quality. All modern browsers support WebP. For maximum compatibility with older systems, use JPG. For graphics with transparency, use PNG.

Yes! You can upload multiple images at once. Free users can compress up to 20 images per day. Pro users get unlimited batch compression. After processing, download all images as a ZIP file.
