Honest limitation
Heavy compression rebuilds pages as images. Text, forms, links, accessibility tags, and digital signatures may be flattened. Keep your original.
What this preset does
A real byte limit, already entered.
PDFPinch works toward a maximum of 500 KB, equivalent to 512,000 bytes. If the original is already smaller, it preserves the original file.
A 500 KB ceiling gives photographs, scans, and several-page documents more room than smaller presets. Complex portfolios or long image-based PDFs may still need splitting or a higher limit.
Scanned certificates
Compare the output with the original, especially when the PDF contains small print or coloured evidence.
Email attachments
Keep digitally signed, editable, or archival originals untouched; compress a separate submission copy.

Before you compress
500 KB questions, answered.

Can the finished PDF be exactly 500 KB?
The tool treats 500 KB as a maximum and aims just below it. An exact byte-for-byte size would add useless padding and is rarely required by upload portals.
What happens if my PDF is already below 500 KB?
PDFPinch keeps the original bytes rather than recompressing an already acceptable file.
How many pages can I compress?
The current browser tool supports up to 40 pages and files up to 40 MB. A long PDF may not remain readable at a 500 KB total limit.

Why a portal may reject a PDF that looks small enough
This preset uses binary units: 1 KB is 1,024 bytes and 1 MB is 1,048,576 bytes. Some portals use decimal units instead. A file displayed as 1 MB can therefore exceed a portal’s 1,000,000-byte limit.
For a decimal 1 MB limit, enter 976 KB or less in the compressor. For a decimal 200 KB limit, enter 195 KB or less. Always compare the downloaded file’s actual byte size with the destination’s stated limit.
Keep the smallest version that is still readable
Remove only pages you do not need, then try the largest permitted target. If small print becomes blurred, a smaller file is not a successful result. Keep your original and check each page before uploading the compressed copy.
