Compress PDFs for Government Portals
Filing with government services, business-registration, tax or benefits portals often means uploading a license, contract or certificate scan that has to be ≤500KB — and an oversized file stops you at the submit button. compress cat's Compress PDF gets you there with a single 500KB preset, locally in your browser and never uploaded. Below: the common limits, how to pass in one go, and what to watch for.
What size limits do government portals usually set?
Standards differ between agencies, but 500KB is a very common single-file cap, and some portals are stricter for an individual certificate. Check the hint next to the upload control before submitting.
- Business licenses and certificate scans: commonly ≤500KB per file.
- Contracts and agreements: many pages and large, so they often need compressing to qualify.
- Format: most accept PDF or JPG and enforce a minimum legibility, so you can't compress to mush.
How do you get a license or contract under 500KB?
A single certificate compresses to 500KB easily; a multi-page contract scan is usually larger and may need its page count trimmed first.
- Open Compress PDF and drag in the license or contract scan.
- Click the 500KB preset.
- Click Start and let the in-browser compression finish.
- After downloading, confirm the license number, stamp and contract text are legible before uploading.
How do you pass on the first try and avoid rejections?
Government filings get bounced for two main reasons: 'too large to upload' and 'compressed until illegible'. The goal is to meet the limit while staying readable, and to organize multiple documents the way the portal expects.
- Keep it legible: license numbers, stamps and contract amounts must stay clear — aim for 500KB rather than smaller.
- Trim pages: for long contracts, remove irrelevant pages with Delete Pages, or keep only what's needed with Split PDF, then compress.
- Combine as required: if the portal wants several documents in one PDF, compress each first and then use Merge PDF.
- Self-check before submitting: zoom in on text and stamps, confirm the size meets the limit, and use a clean filename to cut down on rejections.
Frequently asked questions
How do I get a business license under 500KB?
In Compress PDF, drag in the license scan, click the 500KB preset and Start. compress cat converges on the target locally in your browser; check the license number and stamp are legible before uploading.
The portal requires legibility — could compression fail review?
Not unless you over-compress. Aim for the allowed size (500KB) rather than smaller, then zoom in to confirm the key details are readable. If it's flagged as blurry, loosen the target and re-compress.
Do documents pass through compress cat's servers?
No. Compression happens locally in your browser, so licenses and contracts are never uploaded and stay on your own device.
My contract is several pages and won't reach 500KB — what now?
Remove irrelevant pages with Delete Pages, or keep only the needed pages with Split PDF, then compress; switching unnecessary color scans to grayscale also shrinks the file noticeably.
