    Eligible PDF copies include the original colorful logo with Made, Scanned or Printed with FileFatafat branding in a verified clear area or added footer space. Protected originals, strict formats and size limits take priority. Standalone image exports have no visible watermark. Generated download names include _FileFatafat once. Originals are unchanged.

    When a portal asks for a PDF under 300 KB

    300 KB is a frequent ceiling for certificates, category documents and address proofs on application portals.

    Start with Preserve text, which keeps text selectable and only removes waste inside the file. If that is not enough, Scan-style compression turns each page into an image at reduced quality, which reaches much smaller sizes but removes selectable text, links and digital signatures.

    A published example: NEET UG 2026 asks for several certificates and address proofs as PDFs of 50–300 KB (source: NTA NEET UG 2026 information bulletin, checked 1 October 2026). Requirements change with every cycle, so follow the notification for your own form.

    How to use PDF under 300 KB

    Choose files, review the pages and options, then prepare and download. Clear files to start a fresh session.

    Check the requirements on your form

    PDF editing can invalidate digital signatures and may affect interactive fields, links or annotations. For signed or official originals, use a copy and inspect the output.

    Will my file be uploaded?

    No. Processing happens in your browser, including PDF rendering, scanning and ZIP creation. Tool code is downloaded from this website; the documents you select are not sent back.

    Can every file reach the requested size?

    No. A size limit is a maximum, not an exact guarantee. Detailed or multi-page documents may need a larger limit to remain readable. One KB here is 1,000 bytes. Check clarity and any minimum file size before submission.

    Why can't my PDF get below 300 KB?

    Every page needs a minimum amount of data to stay readable, and FileFatafat stops at a quality floor instead of producing an unreadable file. Remove pages you do not need, or rescan the pages in grayscale, and try again.

    Is there a page limit?

    There is no fixed page-count cap. Browser memory, source size and the work required by compression determine practical capacity; use smaller batches if the device cannot complete it.

    Will the text stay selectable?

    Yes with Preserve text. No with Scan-style compression, which you have to confirm first because pages become images.
