Compress a PDF for GST Registration
The GST registration portal caps uploaded proofs — address, bank and business documents — often around a few hundred KB to 1 MB each (with a JPEG for the photo). Compress your scans to fit while keeping them legible, all in your browser, so nothing is uploaded to a third party.
The requirement
- Document limit
- ≈ up to 1 MB per PDF
- Best for
- Address & bank proof, constitution docs
- Tip
- Greyscale scans start much smaller
- Format
- PDF (JPEG for the photo)
These are typical published values and can change from year to year and from one portal to another. Always confirm the exact requirement in the official notification or upload portal before you submit — the official source takes precedence over anything here.
Step by step
- 1Check the GST portal's size limit for each document.
- 2Open the pre-armed compressor at that target and add your scan.
- 3Download and upload each document to the registration.

Scans store pages as high-resolution images; compressing (or scanning in greyscale) shrinks them a lot.
No — compression runs in your browser, so nothing leaves your device.
