Shrink your PDF files to under 100 KB or 200 KB for government portals and forms. Secure browser-based compression: your files never leave your device.
Who Uses Compress PDF
Compress PDF is the go-to fix for upload size limits and everyday sharing: - **Visa, immigration and government forms**: online forms with a per-file limit, from US agencies to Indian portals (compress PDF to 100kb for UPSC / SSC / banking, 200kb for state boards). - **Bank and KYC uploads**: loan and account documents where the portal caps each upload, such as SBI forms at 1 MB. - **Resume uploads**: HR systems and university admission portals that reject files over 1 MB. - **Email attachments**: fit reports, invoices, and bank statements under Gmail's 25 MB cap. - **WhatsApp & Slack**: shrink scans and reports so they share instantly without server delay. - **Tax filings and invoicing**: attach receipts and invoices to filings and customer emails. Because compression runs locally, sensitive documents like pay stubs, ID copies, and medical reports stay on your device.

Frequently Asked Questions
How much smaller will my PDF be?
It depends 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?
Lossless never re-renders anything. Extreme, Recommended and Less turn each page into a JPEG image when that is smaller, so text in that version can no longer be selected or searched. Image quality depends on the level you pick: "Extreme" recompresses images aggressively (great for scans bound for a 100 KB form upload), "Recommended" is balanced, "Less" 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 tax returns, pay stubs, bank statements, ID scans (including Aadhaar and PAN), medical reports, and KYC paperwork.
How do I compress a PDF to under 100 KB?
Switch to **Target size** mode (next to the quality picker) and tap **100 KB**. The tool runs a quality search and returns the highest-quality output that fits under 100 KB. The same path covers compress PDF to 200 KB, compress PDF to 300 KB, compress PDF to 500 KB, and compress PDF to 1 MB, including custom sizes like 75 KB for state-portal uploads.
Does this work for job, visa and government portal uploads?
Yes, this is what Target size mode is for: job applications, visa and immigration forms, college portals, and Indian portals like SSC, UPSC and SBI. Check the size limit in the portal's own instructions and type it in, or pick the preset that matches. The tool finds the best legible version that fits.
Is my PDF uploaded to your server?
No. Every compression runs entirely in your browser using pdf-lib and pdfjs: files are never uploaded, never logged, never visible to us. No server processing means pay stubs, bank statements, ID scans, medical reports, and other confidential documents stay on your device throughout.
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 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.
