How to compress a PDF
- Upload your PDF by clicking the upload area or dragging the file onto it.
- Choose a compression mode: Recommended for most cases, Extreme if the file is still too large, or High if you need better readability.
- Click Compress and wait while each page is re-encoded for a smaller file size.
- Review the before-and-after sizes and the savings percentage, then download the optimized PDF.
This tool rasterizes pages (text becomes an image), so it's best for scanned documents and form uploads — not for PDFs where you need selectable text.
Why you might need this
Exam and government portals cap document uploads at surprisingly small sizes — SSC and IBPS often ask for under 1 MB, banking forms for under 500 KB, and some state PSC portals for as little as 100 KB. A scanned marksheet or Aadhaar can easily run 3–5 MB straight off a scanner or phone app, which means the upload fails before you even submit the form. This compressor brings those oversize PDFs back under the limit.
Because it works by re-encoding pages as images, it's most effective on scanned documents (marksheets, certificates, ID proofs) where the text is already an image anyway. For text-heavy PDFs where you need to keep selectable, searchable text, this approach will flatten it — use it when the priority is hitting the size cap, not preserving text selection.
If you have multiple PDFs to upload, merge them first, then compress the combined file. Starting from photos? Convert with Image to PDF and then compress the result.
PDF upload size limits on common portals
| Portal / exam | Document type | Typical max size |
|---|---|---|
| SSC / IBPS | Documents (PDF) | 100 KB – 1 MB |
| UPSC CSE | Documents (PDF) | 2–20 MB (varies) |
| RBI / SBI | Documents (PDF) | 500 KB – 1 MB |
| State PSC | Documents (PDF) | Check notification |
| College / scholarship | Documents (PDF) | 1–5 MB |
Always confirm the exact size against the official notification before uploading.
Frequently asked questions
Will this reduce text quality?
This tool rasterizes pages, so text becomes an image. It's best for scanned PDFs or uploads with strict size limits — not for PDFs where you need to copy or search the text.
What compression mode should I pick?
Start with Recommended. If the file is still too large for your portal, switch to Extreme. Use High only if readability matters more than hitting a tight size cap.
Do I need to merge before compressing?
If you have multiple PDFs, merge them first using Merge PDFs, then compress the combined file so the whole bundle fits the limit.
Can it compress encrypted or password-protected PDFs?
No. Remove the password in your PDF reader first, then upload the unlocked file.
Is my PDF uploaded to a server?
No. All compression runs locally in your browser — your document never leaves your device.
How much can I expect the file to shrink?
Scanned documents typically shrink 60–90% depending on the mode. Already-compressed PDFs or PDFs with mostly text may see smaller reductions.
