You don't need to install an app to work with PDFs on a phone. A browser-based toolkit handles the common tasks — merging, splitting, compressing, signing — straight from your mobile browser.
What works well on mobile
Merging, splitting, rotating, compressing, and signing all work in a phone browser. Signing is especially natural on a touchscreen — you draw your signature with your finger.

Phones have less memory than laptops. Very large or many-page PDFs (especially in compression or OCR) can be slow or strain memory, so work with reasonably sized files on mobile.
No install, more privacy
A browser tool means nothing to install, and a local one means your documents never leave the phone.
