Android comes with basic PDF viewing, but editing, signing, and annotating require an additional tool — or just Chrome and pdfeditor.onl.
Any PDF can be opened natively in Chrome on Android or in Google Drive. Tap the PDF file to open it in the default viewer.
Open Chrome and navigate to pdfeditor.onl/pdf-studio. Upload your PDF to add text, annotations, signatures, images, or to erase content.
Tip: For signing PDFs on Android, pdfeditor.onl/sign-pdf is the dedicated tool — optimized for touch input on mobile screens.
After editing, click Download PDF. The file saves to your Downloads folder and is accessible in any Android file manager.
No. Chrome on Android handles the full pdfeditor.onl interface — no app installation required.
Yes — completely free in Chrome on Android.
