Exam tools
The files these portals ask for are identity documents: a face photo, a signature, a marksheet, a caste or income certificate. Sending them to an unknown compressor so they will fit a 50 KB field is the opposite of what the form is trying to protect.
These tools search encoder quality (and scale if needed) until the file is at or under the cap you picked. They do not claim a portal will accept every output — they report the achieved size so you can check the form instructions before you submit.
Browser-side processing is not strictly better, and the last row is the honest cost of it. Here is the trade in full.
| Typical server-based tool | Fileraz | |
|---|---|---|
| Where your exam photos and PDFs are processed | Uploaded to the operator's servers | In your browser tab, on your own device |
| What the operator can see | The file contents, while processing and in any retention window | Nothing — the file is never transmitted |
| Usage limits | Commonly a daily cap or a size cap, with a paid tier above it | No cap, because your conversions cost us nothing to run |
| Account required | Often, for anything beyond the basics | Never — there is no public sign-up at all |
| Speed | Upload time, queue time, then download time | Starts immediately; bounded by your own hardware |
| Large or complex files | Handled well — server hardware does the heavy lifting | Bounded by your device memory, and may fail where a server would not |
Worth knowing before you start, rather than after.
