How image compression works
Photos straight from a camera or phone are far larger than they need to be for the web. This tool re-encodes your image at a chosen quality level, throwing away detail your eye can't notice. The result is a dramatically smaller file that still looks great — perfect for websites, email attachments, and upload limits.
JPG vs WebP vs PNG
- JPG — best all-round compression for photographs. Use 70–80% quality for an excellent size-to-quality balance.
- WebP — a modern format that's usually even smaller than JPG at the same quality, supported by all current browsers.
- PNG — lossless; keeps perfect quality and transparency but produces larger files. Best for logos and graphics, not photos.
Are my images uploaded to a server?
No. Compression happens entirely in your browser using the HTML canvas. Your photos never leave your device.
Will compressing reduce the dimensions?
No — this keeps the original width and height. To change dimensions, use our Resize Image tool.
Why is my PNG not much smaller?
PNG is lossless, so quality settings don't apply. For big savings on photos, choose JPG or WebP output instead.
