FAQ
Is my PDF uploaded?
No. Compression runs inside this browser and the file never leaves your device.
Why did my PDF barely shrink?
Only images are recompressed. PDFs that are mostly text, or whose images are already small, have little to gain. Scanned documents and photo-heavy files usually shrink the most.
Which level should I use?
Light keeps images close to the original. Balanced suits email and sharing. Strong gives the smallest files and also converts lossless images such as screenshots to JPEG, so they may look softer.
