Frequently asked questions
Is my image uploaded to a server?
No. Compression happens entirely in your browser using the canvas API. Your image never leaves your device, so it works even offline after the page loads.
Will compressing make my photo look blurry?
At quality 80, most photos look the same to the eye while shrinking a lot. If you can see a difference, raise the quality to 90 or 95. Below 50, fine detail and smooth gradients start to show visible artefacts.
Which format should I choose?
JPEG is smallest for photos. PNG keeps sharp edges and transparency but is larger, so it only shrinks photos a little. WebP is usually the smallest of all for both photos and graphics, and most modern browsers and apps support it.
Why did my PNG get bigger, or barely shrink?
PNG is a lossless format, so quality settings do not apply to it — the pixels are stored exactly. For a big size saving on a photo, switch the output format to JPEG or WebP. Use it as a free compress image online — no signup, nothing to install.
