Compress PDFs for Government Portals
Government services, business-registration, tax and benefits portals often require license, contract or certificate scans to be ≤500KB. Compress PDF can try reducing them locally, with nothing uploaded. Set a target, choose a method for each file, and review output bytes and pages; reaching the target or passing review is not guaranteed. Below: the common limits, how to check the result, 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?
Whether a certificate reaches 500KB depends on its content and method. A multi-page contract may need a different source export or fewer pages, where submission rules permit it.
- Open Compress PDF and drag in the license or contract scan.
- Enter a target in KiB and compare the displayed bytes with the portal's 500KB limit; a 500 KiB preset is 512,000 bytes.
- Review the per-file method, then click 'Compress files'. Start with 'Keep selectable text'; image compression removes selectable text and may lose detail.
- After downloading, confirm the license number, stamp and contract text are legible before uploading.
What should you check before submitting?
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?
Add the license scan and set a target in KiB whose bytes fit the portal's 500KB limit. Start with 'Keep selectable text', then click 'Compress files'. If you choose 'Compress as images', accept losing selectable text and possibly detail. Check output bytes, the license number and stamp before uploading.
The portal requires legibility — could compression fail review?
Yes. Image compression can blur details, and a portal can apply requirements beyond size. Inspect every page and compare output bytes with the cap. A within-target result does not guarantee acceptance.
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.
