Frequently Asked Questions
How much smaller will my PDF be?
Typically 30–80% smaller, depending on the content. Image-heavy PDFs (scans, photos) shrink the most. Text-only PDFs shrink less since there's not much to compress. The tool always returns whichever is smaller — the lossless rewrite or the image-recompressed version — so you never end up with a result larger than the original.
Will my PDF lose quality?
Text stays crisp at every level — vector text is never re-rendered. Image quality depends on the level you pick: "Smallest" recompresses images aggressively (great for scans bound for a 100 KB form upload), "Recommended" is balanced, "High Quality" keeps images sharp, and "Lossless" never touches image quality at all.
Is my data safe?
Yes. Every compression runs entirely in your browser using pdf-lib and pdfjs — files are never uploaded, never logged, never visible to us. Safe for confidential documents like Aadhaar, PAN cards, salary slips, bank statements, medical reports, and KYC paperwork.
Can I compress a PDF to a specific size like 100 KB or 500 KB?
Yes — pick "Smallest" for the most aggressive compression. Most scanned PDFs can be reduced below 100 KB while staying legible. For multi-page scans bound for UPSC, SSC, IELTS, or banking forms, this level is usually exactly what you need.
Can I compress multiple PDFs at once?
Yes — drop up to 10 PDFs at the same time. Each file shows its own progress bar and final size, and you can download them individually or grab everything as a single ZIP.
What's the maximum file size?
100 MB per PDF, 10 files at a time. The cap exists because everything runs in your browser — much bigger files can stress your device's memory. If your PDF is larger than 100 MB, try splitting it first and compressing the parts.
What if my PDF is password-protected?
The tool will detect the encryption and prompt you to unlock it first. Use our Aadhaar PDF Password Remover to strip the password locally, then come back here to compress the unlocked file.
Does the tool add a watermark or any branding to my PDF?
No. The compressed PDF is byte-clean — no watermarks, no "Compressed by…" footers, nothing added. The output is identical in appearance to the original, just smaller.
