Frequently asked questions
Are my files uploaded?
No. Merging happens in your browser and the files never leave your device.
Is there a limit on the number of files?
The tool shows its limits on the page. Very large files depend on your device’s memory.
Why did my file not get smaller?
Text-only PDFs and files already compressed by their creator have little left to remove. Try Maximum mode if the pages are scans.
Will Maximum mode hurt quality?
Yes, to a degree. Check the result before sending it, and keep the original.
Can I convert HEIC photos from an iPhone?
Convert them to JPG first with the HEIC to JPG tool, then add them here.
