Scholarship forms, exam applications, subsidy portals, tender submissions — almost all of them enforce a PDF size cap, and most people hit it at the worst possible moment.
No upload. No watermark. No sign-up. Every tool mentioned here runs inside your browser.
100 KB or 50 KB — the file will be an image; expect degradation. Usually for a single certificate or photo page.
200 KB — the most common cap. One or two pages stay readable.
500 KB — comfortable for a scan of a few pages.
1–2 MB — typical for tender documents, GST replies and multi-page submissions.
Delete blank pages and duplicates. Crop white margins — a scan with wide borders wastes a large share of the budget.
Rotate pages so they are upright; sideways scans are often re-rendered larger. If the document is only text, try Safe mode first — it keeps the text selectable and sometimes is enough on its own.
Check the error text. Portals also validate page dimensions, DPI, colour mode, page count and sometimes whether the PDF is encrypted.
Common fixes: convert colour to grayscale, flatten form fields, remove the password, or reduce the page count. A file can be 90 KB and still be rejected for being 300 DPI RGB instead of 200 DPI grayscale.
Always keep the uncompressed original. Portals change their limits, and re-compressing an already-compressed file compounds the damage.
If you need to submit twice, start again from the original.
Only if the file never leaves your device. This site processes everything in your browser, so an Aadhaar scan is never transmitted.
Rarely for a scan. Crop to the content, convert to grayscale, and accept that fine print may soften.
