PDF tools FAQ

How do I find hidden text in a PDF?
Drop the file on PDF X-Ray. It scans in your browser for invisible text, white text, leftover incremental saves, JavaScript, attachments, and metadata — then gives you a downloadable report.
What does X-Ray actually look for?
Leftover incremental saves (old wording still in the bytes), invisible and white text, text sitting under a painted “redaction,” JavaScript and open-actions, embedded/attached files, form values, layers, identity metadata, and EXIF/GPS left in embedded JPEGs.
Does this delete the hidden data?
No. X-Ray is a scanner, not a cleaner. It tells you what is still in the file. Use Compress (High) to flatten pages if you need a visual-only copy — that still is not a certified redaction tool.
Will you see what’s hidden in my PDF?
No. The scan runs in your browser. Findings never leave the device. Analytics only records that the X-Ray tool was used, not the file or the findings.
Is it safe to compress or convert a PDF online?
Yes — on UnlimitedPDF.app the file never leaves your device. Compress PDF, merge PDF, split PDF, and PDF to Word all run in your browser. We cannot see your documents because they are never uploaded to a server.
Is there a free PDF compressor with no file size limit?
UnlimitedPDF does not cap file size or daily use. There is no sign-up and no watermark. The only ceiling is your browser’s memory. Very large PDFs are more reliable on a desktop than on a phone.
Do I need an account to merge PDF files or convert PDF to Word?
No. Every tool works without an account: compress PDF, merge PDF files, split PDF, JPG to PDF, PDF to JPG, resize image, and PDF X-Ray. Optional sign-in never unlocks a paid tier — there isn’t one.
How is UnlimitedPDF different from iLovePDF or Smallpdf?
iLovePDF and Smallpdf typically upload your file, then limit size or daily use unless you pay. UnlimitedPDF is a free online PDF editor toolkit that processes locally — no upload, no size cap, no watermark. The tradeoff is your browser’s RAM, not a subscription.
Can I compress a PDF without uploading it?
Yes. Drop the PDF on Compress PDF, pick Low, Recommended, or High, and download. Re-encoding happens in this tab. Same for merge, split, and convert — nothing is sent to our servers because there is no file-upload endpoint.
