Convert to JPG
Convert to JPG turns PNG, WebP, GIF, BMP and HEIC images into standard JPG files in one batch. JPG is the format every system accepts, which makes this the safe choice when a portal rejects your modern-format upload.
How to use Convert to JPG
- Add the images you want as JPG.
- Set the output quality if you want a specific balance of size and fidelity.
- Convert and download the JPG files.
Where Convert to JPG is useful
- Making a WebP or HEIC photo acceptable to an upload form.
- Flattening PNGs with transparency for a system that cannot handle alpha.
- Standardising a mixed folder of images for printing.
Formats, algorithms and limits
The image is drawn onto a canvas and encoded as JPEG, which is lossy and has no transparency channel. Transparent areas are filled with white, and HEIC conversion depends on your browser's own decoder — if your browser cannot read HEIC, convert it once on the device that captured it.
Troubleshooting and honest limits
- Use quality 85 or above for images with text; JPEG artefacts are worst around sharp letterforms.
- Check the output if the source had a transparent background — the flattened result is white behind the subject.
- Keep the original PNG or WebP if you may need transparency again later.
Frequently asked questions
Will my transparent PNG get a white background?
Yes. JPEG has no alpha channel, so transparency is flattened. If you need transparency, keep PNG or use WebP instead.
Can I convert HEIC photos from my iPhone?
It works when your browser can decode HEIC; otherwise convert once on the phone (iOS shares as JPEG by default) and use the JPG here.
Does converting to JPG lose much quality?
There is one generation of JPEG compression. At quality 85+ the loss is invisible at normal viewing sizes, but repeated re-saving compounds it.
How many files can I convert at once?
As many as you like — the queue processes each image locally with no server-side limit.
