PDF tools
Reduce a PDF to under 500 KB for online forms.
Upload a PDF to make it smaller than 500 KB.
Strong compression is tried first so your text stays selectable. If that is not enough, pages are turned into lighter images to fit the limit.
Upload forms often refuse PDFs above 500 KB, especially for email attachments and online forms. This tool makes your PDF fit: it first applies strong compression, which keeps your text selectable. If that is not enough, it turns the pages into lighter images at the best quality that still fits under 500 KB.

Yes. Type any size in the Maximum size in KB field, for example 300 KB or 2000 KB.
