Frequently asked questions
Are my images uploaded somewhere?
No. Compression happens entirely in your browser through a canvas element. The file never leaves your device.
What quality should I pick?
80% is a good default for photos, balancing visible quality with file size. Drop to 60–70% for thumbnails or social posts.
Why does PNG sometimes get larger?
PNG is lossless. The quality slider mainly affects JPEG and WebP. PNG benefits more from resizing than from quality changes.
