Choose your PDF below — the 1 MB target is already selected — and tap Compress. The tool finds the best quality that fits under 1 MB. A 1 MB PDF typically holds about 12–25 scanned pages at readable quality.
Tips to fit a PDF under 1 MB
- Upload only the pages asked for — use Split PDF to extract them first.
- Black & white makes scanned text sharper and files much smaller.
- Scan at 150–200 DPI, not 600 DPI — higher resolution only adds size.
- Documents are photos? Convert JPG to PDF first, then compress.
Getting documents right for online forms
- Check the exact limit first. Portals state the format (PDF or JPG) and a maximum size such as 100 KB, 200 KB or 1 MB. A file even 1 KB over is rejected.
- Scan at 150–200 DPI. That is sharp enough to read and keeps files small. 600 DPI scans only make files bigger.
- Upload only the pages asked for. Remove blank or extra pages with Organise PDF before compressing.
- Password-protected PDFs (for example e-Aadhaar or bank statements) must be opened and saved without a password before most portals — and these tools — can use them.
- Name files clearly, e.g.
10th_marksheet.pdf, and open the final file once to check every page is readable.
