Limits change, so check the official notice before you upload.
01
Per page or per file?
Read the limit carefully. Protean's PAN form allows up to 300 KB a page, while other forms cap the whole file. If the limit is per file, shrink the full PDF to 300 KB; if it is per page, a file of several pages may be allowed to be larger, so check the form.
02
Your file stays on your device
Some online compressors send your file to their servers. This one works inside your browser, so a PDF of your marksheet, ID or bank statement never travels anywhere. Close the tab and the tool keeps no copy.
03
The text becomes an image
The smaller copy is made of page images, so its text can no longer be selected; a form that only needs to see the page will usually accept that. The DigiSafe app makes a copy at any size from 10 KB to 20 MB on your phone, and keeps the original encrypted for the next form, free today, with no ads.
Questions about 300 KB PDFs
How do I compress a PDF to 300 KB?+
Choose your PDF in the tool on this page, keep 300 KB selected and tap Shrink. The smaller PDF downloads in your browser, and your original is not changed.
Which forms ask for a PDF under 300 KB?+
Among those our guides cover: Protean's PAN form (up to 300 KB a page), NEET UG 2026 certificates (50 to 300 KB) and the Indian e-Visa passport page (up to 300 KB). Each guide links the official source.
Will Protean's PAN form accept this PDF?+
Protean asks for documents as black and white PDF/A or JPEG, up to 300 KB a page. This tool makes a standard colour PDF, not PDF/A, so scan in black and white first and check the form accepts it, or upload JPEGs made with the free PDF to JPG tool.
