How to use this tool
JPG, PNG and WebP: what changes?
JPEG is a common format for photos but does not support transparent backgrounds. PNG is generally useful for graphics, transparency and crisp diagrams, though some files are large. WebP supports lossy or lossless encoding and may be smaller. Re-encoding does not restore information that was already lost; converting an old JPEG into PNG will not recover missing detail.
How to convert an image
Select up to six JPG, PNG or WebP files, choose the output format and optional maximum dimension, then click Convert. The browser decodes each image and writes it back in the selected format. Filenames are updated to match the extension. When exporting JPEG, transparent pixels are filled white; PNG and WebP may preserve transparency depending on the source and browser.
What about animated GIF or HEIC?
This first version is designed for still JPG, PNG and WebP images. It does not support HEIC directly or preserve animation from GIF or animated WebP; a decoded frame may be all you get. For those formats, use a tool designed to handle their special metadata. Some browsers do not offer WebP export, so a format option may fail with a clear message.
Privacy and quality
Your pictures remain in the browser: we do not upload them or keep copies. Canvas exports usually omit original metadata, including camera settings and location. JPEG quality can be adjusted; PNG output is usually larger because it preserves pixel detail without JPEG-style loss. Check the converted file before sharing it or deleting the original.
Frequently asked questions
Will converting JPG to PNG improve quality?
No. PNG may preserve the current pixels, but it cannot recreate details lost during previous JPG compression.
Can I convert a transparent PNG to JPG?
Yes, but JPEG does not support transparency. Transparent areas are filled white.
