A comfortable size for sharing
500 KB is a sweet spot: small enough to email instantly on mobile data and to pass most upload forms, and large enough to keep multi-page documents looking almost like the original. It’s a common requirement for bank, insurance and loan paperwork, and a sensible target any time you share a scan by email or chat.

What fits under 500 KB
- Statements and bills: around 10 scanned pages with crisp tables and figures.
- Insurance claims: a claim form plus a few supporting bills or reports.
- Reports with charts: most stay lossless, with nothing changed visually.
Why smaller attachments help
Big attachments are slow to send on weak connections, fill up shared mailboxes, and are sometimes blocked by company mail systems. Keeping documents around 500 KB means they arrive quickly and open instantly on the recipient’s phone.
How Atifo keeps quality high
Because 500 KB leaves room, Atifo usually picks high-resolution settings, often close to what you’d use for printing. It aims just under the limit rather than as small as possible, so you don’t give up quality you could have kept.
Very long documents
A 100-page scan squeezed into 500 KB would be hard to read. If your document is that long, Atifo will say the target can’t be met at a readable quality. Splitting it into sections, or sending only the pages that are needed, works better.
Your files stay private
Financial documents are processed in your browser and never uploaded.

Frequently asked questions
How good does a 500 KB PDF look?
Very good for most documents. A 10-page scanned statement typically fits at a quality that is hard to tell apart from the original on screen.
Why compress to 500 KB if email allows more?
Smaller attachments send faster on mobile data, fit within shared-inbox limits, and are less likely to be blocked by company mail filters.
Can I compress bank statements safely?
Yes. Statements are processed only in your browser and are never uploaded, which makes Atifo a safe choice for financial documents.
What about very long documents?
For 100+ page documents, 500 KB may be too tight to stay readable. Atifo will say so; splitting the document into parts is usually the best option.
