How to use the image format converter
Upload an image, pick the format you need and adjust the quality if you are converting to JPG or WebP. When converting a transparent PNG to JPG, choose the background colour that should fill the transparent areas. The converted image appears with its new size, ready to download. Nothing is uploaded to a server.
Why format matters
Different platforms accept different formats. An older CMS may reject WebP, an email client may struggle with large PNGs, and a fast website benefits from WebP. A reliable converter bridges the gap between the file you have and the file you need.
Common uses
- WebP to JPG for an older CMS or email tool
- PNG to JPG for smaller attachments
- Photos to WebP for a faster online store
- Transparent PNG to JPG with a matching background
Transparency turns solid when converting to JPG
JPG does not support transparency, so transparent areas are filled with a solid colour. White is the default. If the image will sit on a coloured background, pick that colour instead so the edges blend in.
Frequently asked questions
Will I lose quality?
Converting PNG to JPG or WebP loses a little detail, controlled by the quality setting. Converting JPG to PNG loses nothing more, but the file is usually larger because PNG is lossless.
Can I convert several images at once?
This tool converts one image at a time. For large batches, a command line tool like ImageMagick is faster.
Can it convert HEIC photos from an iPhone?
Most browsers cannot read HEIC files. Export the photo as JPG from your phone or computer first, then convert it here if you need another format.
Should I always use WebP?
For websites, WebP is a strong default because all modern browsers support it. For email, JPG and PNG are safer since some email clients do not display WebP.
