Compress PDF to 500 KB now

The comfortable middle

500 KB is the most forgiving of the common portal limits and the one that rarely forces a real compromise. A handful of scanned pages fits at a resolution that stays crisp on screen and acceptable in print.

Because there is headroom, this is the target where the Keep text mode is worth trying before Scan mode. Keeping the text layer means the document stays selectable and searchable, which matters if anyone downstream needs to copy a reference number out of it.

Reach for Scan mode only if Keep text cannot get you under the limit — it produces smaller files, but it turns every page into a picture of a page.

Scan mode or Keep text?

This is the only decision that really changes the result, and it depends on what your PDF already contains.

• Keep text leaves the text layer alone and compresses the images around it. The document stays selectable, searchable and copyable. The reduction is smaller, which is fine whenever the target has headroom.
• Scan mode rasterizes each page into an image and compresses that. It reaches much smaller files, and it is the right choice for documents that were scanned or photographed in the first place — they have no text layer to preserve.

The trap is using Scan mode on a document that was born digital. You get a smaller file and lose the ability to search it, select a reference number from it, or have a screen reader read it aloud. Try Keep text first and only fall back to Scan mode if the target demands it.
