Image Format Converter

Convert PNG, JPG/JPEG and WebP images — one at a time or a whole batch — right in your browser with the Canvas API. Choose an output format and quality, and download files individually or as one ZIP. No uploads, fully private.

Quick Answer: Which image format do government portals accept?

JPG is the safest default for bank, GST and email image uploads — accepted everywhere and small. Note: e-Sanchit itself accepts PDF only (under 1 MB, about 75 KB per A4 page, max 13 pages) — convert your scan to JPG here, then use our OCR PDF Generator to build the portal-ready PDF. Use PNG when you need transparency or lossless text (logos, signatures) and WebP only where modern formats are welcome. This free image converter re-encodes PNG, JPG and WebP right in your browser — single files or an unlimited batch, with quality control. Nothing is uploaded; conversion runs entirely on your device via the Canvas API, so invoices and statements stay private.

Download Instantly

Single files download on the spot; batches come back as one ZIP or individual files — portal-ready.

Convert

Drop one image for a single conversion, or several for a batch.

Output Format

Converted image and size comparison appear here.

Privacy first: conversion happens entirely in your browser via the Canvas API. Files never leave your device — safe for invoices, bank statements and commercial documents.
Common conversions
  • ● JPG → PNG for logos and signatures that need transparency
  • ● PNG → JPG to shrink photos and scanned pages for email
  • ● WebP → JPG when a portal rejects modern formats
  • ● Batch-convert a whole scan folder in one go

Next step: need smaller files for portal limits? Use the Image Compress & Resize tool, and for e-Sanchit’s PDF-only rule turn the converted JPGs into a ≤1 MB PDF with the OCR PDF Generator. And before you e-file, stamp your signature on documents free with the PDF Signature Pad.

What is Image Format Conversion

Image format conversion re-encodes a picture from one file format to another — for example turning a PNG screenshot into a JPG, or a WebP download into a format an older system accepts. Government portals, banks and email systems in India often accept only specific formats: banks and GST portals accept JPEG images readily, while ICEGATE’s e-Sanchit module requires each supporting document as a PDF under 1 MB (about 75 KB per A4 page, maximum 13 pages) — so convert scans to JPEG here first, then bundle them into a PDF. PNG preserves the transparency needed for signatures, logos and stamps. This tool re-encodes your images using only the HTML5 Canvas API on your device — files are never uploaded, so invoices, statements and ID scans stay private.

Frequently Asked Questions

Which format should I use for uploads?

JPG is the safest default — accepted everywhere and small. Use PNG when you need transparency or lossless text (logos, signatures). WebP is great for web use but some older portals reject it.

Can I convert many images at once?

Yes. Select or drop multiple images and the batch converts them one by one. Choose 'Download all as one ZIP' for a single archive, or leave it unticked to download each file individually. There is no file-count limit — unlike most free online converters that cap batches at around 15 files.

Does conversion reduce image quality?

JPEG and WebP use lossy compression — higher quality slider values preserve more detail at the cost of file size. PNG is lossless and never loses detail, but files can be larger.

Which format does e-Sanchit or ICEGATE accept?

For bank, GST and email image uploads, JPEG is the safest choice — universally accepted and small. For signatures, logos and stamps that need a transparent background, convert to PNG. Avoid WebP for government portals, which commonly reject it. Important: ICEGATE’s e-Sanchit module accepts supporting documents in PDF format only — under 1 MB, roughly 75 KB per A4 page, with a maximum of 13 pages per document — so convert your scans to JPEG here and then assemble the PDF with the OCR PDF Generator.

Are my images uploaded?

No. Conversion happens in your browser using the Canvas API — your images never leave your device.

Is the Image Format Converter free to use?

Yes. The Image Format Converter is 100% free for personal and commercial use — no registration, login or payment required.

Is there a file size or batch limit?

There is no file-count limit, and no server upload limit because files never leave your device. In-browser conversion is bounded by device memory: browsers rasterise images up to roughly 16 megapixels, so extremely large scans may fail — downscale them first with the Image Compress & Resize tool.

Can I convert HEIC photos from my iPhone?

No. Browsers cannot decode Apple's HEIC format. Convert the photo to JPG on your iPhone first (in iPhone camera settings, choose the 'Most Compatible' format), then use this tool for PNG or WebP conversions.
