Increase PDF Size

Some portals and printers reject files below a minimum size. This tool pads your PDF with an invisible, inert attachment to hit an exact target - the document itself is untouched.

Padded locally in your browser - never uploaded

How it works

  1. Drop your PDF

    See its current size right away.

  2. Pick a target

    Type an exact size or tap a preset - 1 MB, 5 MB, whatever the form demands.

  3. Download

    The padded PDF lands within a hair of the target and opens exactly like the original.

FAQ

Does padding damage or change the document?
No. The padding is a standard PDF embedded-file attachment filled with random bytes - invisible when reading or printing, and every page, font and image stays byte-identical. Any PDF viewer opens it normally.
Why would a site require a minimum file size?
Usually a legacy validation rule (e.g. 'photos must be > 1 MB to ensure quality') or an enterprise DMS quirk. Padding satisfies the rule without altering your content.
Can I make it exactly N megabytes?
Within a fraction of a percent, yes - a small fixed container overhead (a few hundred bytes) means the final file lands at 99.9-100.1% of the target.
Is my file uploaded?
No, the padding happens entirely in your browser.
