Key facts
- Common portal limits are 50 KB, 100 KB, 200 KB, 500 KB and 1 MB per document.
- Set the exact limit and the tool keeps the highest quality that fits.
- Certificates, marksheets and ID proofs stay legible — stamps and signatures included.
- Your documents are processed on your device — never uploaded, which matters for ID proofs.
How to compress PDFs for online application forms
- Read the size limit in the form's instructions (e.g. “max 100 KB”).
- Set that size above and drop all your documents at once.
- Download them as a ZIP and upload each to the portal.
Typical document size limits
| Document | Common limit | Tool |
|---|---|---|
| Signature, declaration | 10–50 KB | PDF to 50 KB |
| ID proof, caste/income certificate | 50–100 KB | PDF to 100 KB |
| Marksheets, degree certificate | 100–300 KB | PDF to 200 KB |
| Experience letters, CV | 300 KB–2 MB | PDF to 500 KB |
Always follow the exact limit stated in your form; these are only common patterns.
Avoiding rejection
- Scan in grayscale unless colour is required — it's the biggest single saving.
- Scan just the document, not the whole scanner bed; crop margins.
- We count 1 KB as 1000 bytes, so files pass sites that use either 1000 or 1024. If a portal still rejects a file, check its dimension, format and page rules.
- Don't password-protect the PDF; portals often can't open protected files.
Frequently asked questions
Will a compressed certificate still be accepted?
Yes, as long as it is legible. We keep text and stamps readable and never add a watermark.
Can I compress all my documents at once?
Yes. Drop them together, set the size once, and download a ZIP.
Are my PDFs uploaded to a server?
No. Compression runs entirely inside your browser using JavaScript and WebAssembly-grade libraries. Your file never leaves your device, so confidential documents stay private. You can even disconnect from the internet after the page loads and it keeps working.
