Frequently asked questions
Is this GST filing prep tool free?
Yes — completely free with no sign-up and no limit on how many files you prepare.
Is my document uploaded anywhere?
No. Compression and splitting both happen entirely in your browser — the file never leaves your device.
What upload limit should I choose?
It depends on the specific GST portal form — 5 MB is common for SCN replies and many annexures, 10 MB for some appeals. Check the exact limit on the upload page you're using before filing.
What happens if the file still doesn't fit after compressing?
It's automatically split into several smaller PDFs, each under your chosen limit, delivered as a ZIP — so you can upload them as multiple attachments if the portal allows it.
Will compressing make scanned text hard to read?
The tool tries high quality first and only drops to medium or low if needed to hit the size limit, so quality is only reduced as much as necessary.
