Compress PDF to 500 KB
500 KB caps show up on learning platforms, invoice and expense systems, insurance forms and most “professional” web uploads. It is generous enough to keep a document looking sharp and strict enough to require real compression on image-heavy files — this page opens the tool pre-set to 500 KB.
Get under a size limit
Picking a size limit automatically turns pages into compact images and dials quality down until the file fits. Nothing is ever uploaded — compression happens entirely in this tab.
Getting under 500 KB without regretting it
Assignments with figures
Charts and diagrams stay readable at the automatic 500 KB setting; gradients and photos are where the file size actually goes.
Invoices and receipts
A four-page invoice with a logo compresses to 100–200 KB without any visible change to numbers or tables.
Nothing is uploaded
The whole reduction happens in this tab, so confidential invoices and contracts never touch a server.
Good to know
Is 500 KB considered high quality?
For a text document, yes — you will not see the difference on screen. For photo-heavy pages, expect a mild softening.
Can I compress a PDF with images and tables?
Yes. Tables re-render cleanly; if you rely on very fine grid lines, check the preview on the first page before downloading.
Is there a page limit?
No hard limit — processing happens on your device, so very large files depend on your browser’s memory rather than any server quota.
