Do I register to compress a 5 MB PDF?

No. Eligible files on the free path download without an account.

Why would I still see Pro?

The file is over 12 MB, you queued multiple PDFs, or you need dedicated worker time for a stubborn scan. Those are capacity limits, not a quality paywall.

Is the free output watermarked?

No. Eligible compressed PDFs are unmarked.

Does free mean the file stays on your servers?

No. HTTPS in, delete after download. This path is not Instant-local like Organize PDF.

One file at a time. Folder queues are Pro so the tab is not encoding a stack.

Is Ghostscript different on free vs Pro?

The presets are the same. Pro mainly raises size and concurrency.

What “free” means on this compressor

Free is a size and volume limit, not a quality downgrade. The same Ghostscript presets run for a 4 MB invoice as for a Pro job. Signup appears when you need higher caps or a queue of files, not when you want to save a readable PDF.

Included without an account

Single eligible files up to 12 MB. HTTPS upload, Ghostscript on the worker, auto-delete after download. Light, Balanced, and Maximum are all available.

What we charge for

Bigger documents, multi-file queues, and dedicated VPS capacity when a browser-and-Edge path would stall. We do not sell OCR on this tool — compression is not text recognition.

Siblings that never upload

Merge, Split, and Organize Instant keep bytes on the device. This compressor is a VPS job, so privacy here means HTTPS plus deletion, not local-only encoding.

How it works

1
Skip the account form
If the file is within the free cap, you never need an email.
2
Drop and pick a preset
Light for digital text, Balanced for scans, Maximum for named KB caps.
3
Download and confirm size
Open the result, then attach or archive. We do not keep the upload.

Use cases

One invoice, one send

Freelancers shrinking a single PDF before billing — no product account required.

Shared library PC

No login leftover on a public machine. Download and close the tab.

Comparing with quota sites

Some converters burn a daily cloud quota. Eligible jobs here do not require that dance.

Problems we solve

Download locked behind email

That is the pattern this page is built to avoid for eligible files.

Watermark on the “free” file

Standard output is unmarked. We do not stamp Convertify4u on compressed pages.

Surprise Pro at the last click

If you are over 12 MB or queuing a folder, the upgrade is shown as a capacity gate, not a trick.

Trust & privacy

12 MB free cap, stated

The hub and this page agree on the number.

Same presets

Free is not a blurrier encoder.

Auto-delete

Uploads do not become an account library.
