Good to know
Where a 500 KB limit usually comes from
The GST portal's limit for place-of-business proofs such as an electricity bill, consent letter, property tax receipt or municipal khata copy. Always check the size printed next to the upload button on the portal itself, because limits differ between forms and change over time.
Will it still be readable?
At 500 KB, most documents of a few pages stay clear. Text remains sharp because only the images inside the PDF are reduced.
If it will not go small enough
You are told plainly and given the smallest readable version. We never hand back a file over 500 KB while saying it fits. The usual fix is to remove pages the portal does not need, or to scan in black and white instead of colour.
Questions
How do I compress a PDF to 500 KB?
Open this page, drop the PDF in, keep the 500 KB target selected and press Compress PDF. PDF Sevak compresses, measures, and repeats with finer settings until the file is under 500 KB.
Is compressing a PDF to 500 KB free?
Yes. There is no sign-up, no watermark and no daily limit for single files.
Is there a file size limit?
Up to 100 MB per file. Compression runs in your browser, so very large files depend on your device's memory; on phones, files up to about 50 MB work best.
