How it works
Most clear photos and scanned documents convert under 400KB in one step. If your file is above 400KB after conversion, the second tool handles compression. Both are free with no sign up.
Open Zappy JPG to PDF
Go to zappy.tools/jpg-to-pdf/ on any device — mobile or desktop. No sign up needed.
Upload your JPG, PNG or JPEG
Drag and drop or tap to browse. Select one or multiple images — Zappy merges them into a single PDF automatically.
Download the PDF
Download immediately. Check the file size — right-click → Properties (Windows) or Get Info (Mac). Many clear photos are already under 400KB at this step.
Compress to 400KB if needed
If the PDF is above 400KB, open Zappy Compress PDF, upload, set target to 400KB and download. Done — no sign up, no watermark.
Why it matters
Government portals, visa applications and university admissions require documents in PDF format — not raw JPG or PNG — because PDF is a consistent, device-independent format that portals can process and archive reliably. The 400KB size limit reduces server load and speeds up processing. Uploading a large JPG converted to an uncompressed PDF is one of the most common reasons document uploads get silently rejected.
Which size do you need?
Different portals have different limits. Here's a quick guide — Zappy handles all of them with the same two-step process:
Need 200KB instead? See our guide on JPG to PDF under 200KB. Need to compress a PDF that's already converted? See compress PDF to 400KB.
For India
Indian Railway (IRCTC) requires ID and address proof documents as PDFs under 400KB. Visa application portals like VFS Global require supporting documents in the same format. Many university and college admission portals also cap uploads at 300–400KB per document.
The process is the same for all: upload your JPG or photo to Zappy JPG to PDF, convert, check the size, and compress to 400KB if needed. Works on mobile — no laptop, no software, no cyber cafe visit required.
