How to compress for a portal

Balanced first, Strong if the form still says no.

  1. 1

    Add a PDF

    Drop one PDF — a scan, export, or email attachment.

  2. 2

    Tune compression

    Pick Strong, Balanced, or High — then fine-tune with the slider.

  3. 3

    Download

    Save the smaller PDF — free, no watermark, no account.

Private by design

Compress PDF is built to run in your browser. Your documents stay on your device — we do not upload them to our servers or keep a copy of your files.

That is the same privacy model as Filvo image tools: process locally, download, done.

In one sentence

Filvo PDF Compressor shrinks scans and exports in the browser. Tune size versus quality locally — no upload, no account, no watermark.

Filvo vs typical cloud tools

These tools run in the browser. The file is not uploaded to Filvo for the job.

How to compress a PDF for an upload form

Portals reject the file first and explain later.

This page is the compressor with Balanced already selected — a middle ground for forms that want “under X MB” without destroying stamps.

If the result is still over the cap, drop quality. If it looks soft, go High and split the pack instead.

Steps

Upload the unlocked PDF. Read the new size. Download. Try the portal. Keep the original.

Frequently asked questions

Portals reject the file first and explain later.

Depends on the source. We show the new size before you download. We do not target a specific MB.
