FreeJPG2PNG is a free, browser-based image converter. Every conversion happens on your own device — your files are never uploaded to a server, there is no account to create, and there are no daily limits.
The site offers 210 converters across 16 image formats: JPG, PNG, WebP, GIF, BMP, AVIF, SVG, TIFF, HEIC, ICO, JPEG XL, TGA, DDS, PPM, PGM and PBM. Every converter works with a single file or a whole batch, shows a thumbnail preview of each file, lets you remove files before converting, and downloads the results one by one or as a single ZIP.
Why convert in the browser?
Most converter sites upload your files to their servers. That costs time, needs a good connection, and means trusting someone else with your photos. FreeJPG2PNG does the work where the files already are — in your browser — using the Canvas API and small format libraries. It is faster, it works offline once the page has loaded, and it is private by design.
What you will not find here
No accounts, no email addresses, no sign-up forms.
No watermarks on your images.
No fake converters — if a format cannot be created in a browser (SVG and HEIC as outputs), the site says so plainly instead of pretending.
