Why nothing is uploaded
- Files never reach a server, so there is no path for them to leak.
- There is no size limit, because no server receives the file.
- Conversion finishes on your device, so there is no queue.
Questions
- Is nothing really uploaded?
- Correct. Conversion runs in a Web Worker in your browser, and the resulting file is created locally and handed straight to you.
- Can I convert several files at once?
- Yes. Drop multiple images and they are processed one by one with a progress bar.
Which image formats can I convert?
You can move between PNG, JPG (JPEG) and WebP. JPG for sharing photos, PNG when you need a transparent background, WebP to make a site lighter — switch to whatever the job needs. Converting PDF files online happens on the same screen.
Photo and web image conversion
- Free JPG to PNG: for editing with transparency or working at high quality
- Free PNG to JPG: lighter for sharing and uploading
- Free Webp to JPG and Webp to PNG: ready wherever compatibility matters
- PNG, JPG and WebP between each other: images for websites, blogs, online shops and social media
AVIF — the modern, most efficient format
Where your browser supports it we convert to AVIF as well. It suits web images you want smaller still.
Making icons for apps and websites
From an original PNG you can build these icon files.
- Free PNG to ICO: Windows and website favicon
- Free PNG to CUR: mouse cursor
- Free PNG to ICNS: macOS application icon
When icons are built the original PNG is never re-compressed, so the starting quality stays exactly as it was.
Combining images into one PDF
Pick PDF as the output format and you convert PDF files online right here. Drop in several images and press «Download all» — they come down combined into a single PDF.
- Free PNG to PDF: keeps the transparent areas and stores them with no loss
- Free JPG to PDF: photos go in exactly as they are, with no re-compression
Each PDF page is the real pixel size of the image — we do not stretch it or add margins just to force it onto A4.
Resizing
Type a width and height, or pick one of these. Print sizes are at 300dpi, and nothing is ever enlarged beyond the original.
