Why 500 KB is a sweet spot
500 KB is generous enough to keep scanned documents genuinely print-quality for up to about ten pages, yet small enough for strict portals, insurance claims, visa document checklists and support tickets that cap attachments at half a megabyte.
What you can fit in 500 KB
| Document | Typical result |
|---|---|
| 2–4 page scanned contract | Near original, about 130–150 dpi |
| 6–10 page bank statements | Clear text, fine for printing |
| 15–20 page scanned report | Readable on screen, softer in print |
| Photo-heavy brochure | Good, with some photo detail lost |
Keep text sharp
- Scan text documents at 200–300 dpi in greyscale; the tool will choose the output resolution.
- Avoid compressing an already compressed PDF: every pass loses a little detail. Start from the original.
- If only a few pages matter, cut the rest with Split PDF to give them more of the 500 KB budget.
- Need it smaller still? Try 200 KB or 100 KB.
Frequently asked questions
Will links and bookmarks survive?
No. Pages are rebuilt as images to reach the target, so links, form fields and bookmarks are removed. The visible content stays the same.
How long does it take?
Usually a few seconds for short files. Large scans can take longer because the tool may test more than one quality level.
Are my files private?
Yes. Everything happens in your browser; nothing is uploaded or stored.
