Frequently asked questions
Can I trust this tool with a 100 MB file?
Yes—the tool accepts PDFs up to 100 MB and processes up to 5 files at once. Everything runs locally in your browser, so file size doesn't mean uploading anything.
Will my PDF actually reach 50 MB?
It depends on your document. Photos and scans compress significantly, while already-optimized text-only PDFs may shrink only slightly. The tool shows you the actual result so you can decide whether to keep it.
What happens if compression makes my file bigger?
If a PDF is already highly optimized, the tool keeps the original file unchanged and lets you know. You won't accidentally end up with a larger file.
Will text still be selectable after compression?
No—each page is re-rendered as an image, so text in the result is no longer selectable or searchable. This trade-off is why compression works so well on photo-heavy documents.
