Who Uses Compress PDF
Compress PDF is the go-to fix for India-specific size limits and everyday sharing constraints: - **Government & exam forms** — compress PDF to 100kb for UPSC / SSC / banking portals, compress PDF to 200kb for state-board exams, compress PDF to 500kb for IELTS and tertiary-education uploads. - **Bank & KYC uploads** — compress PDF to 1mb for SBI / PSU forms, compress PDF for Aadhaar e-KYC re-submissions, compress PDF for SBI form attachments where the portal caps each upload 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. - **GST filings & invoicing** — attach line-item PDFs to filings and customer mailers. Because compression runs locally, sensitive documents like salary slips, Aadhaar copies, and medical reports stay on your device.

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: "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 Aadhaar, PAN cards, salary slips, bank statements, 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 Aadhaar, SSC, UPSC, and SBI form uploads?
Yes — these are exactly what the Target size mode was built for. UPSC and SSC application portals cap PDF uploads at 100–500 KB, SBI and other PSU banking forms usually allow up to 1 MB, and Aadhaar / e-KYC portals fall in the 100–300 KB range. Pick the preset that matches your form's limit and the tool finds the best legible scan that fits. Compress PDF for Aadhaar, compress PDF for SBI form, and similar Indian government use cases are the primary supported workflow.
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 salary slips, bank statements, Aadhaar / PAN 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 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.
