Website only accepts JPG? Convert your image on Mac
Convert the image to JPEG before uploading it. On a Mac, right-click the image in Finder and choose FileMate › Convert Image › JPEG. This works for HEIC photos from an iPhone, PNG screenshots, WebP images saved from the web, TIFF scans and other formats. The JPG is saved next to the original. Preview’s File › Export does the same, one image at a time.
The image is converted on your Mac, not on another website.
Make a JPG with FileMate
- Right-click the image in Finder.
- Choose FileMate › Convert Image › JPEG.
- Upload the new .jpg file, which sits next to the original.
If the JPG is over the form’s size limit, right-click it and choose Compress Image.
JPG, JPEG: same thing
.jpg and .jpeg are the same format. Old versions of Windows allowed only three-letter extensions, so .jpg stuck. A form that asks for JPEG accepts .jpg, and the other way round. FileMate saves .jpg.
Which images need converting
| Your file ends in | Where it usually comes from | Convert? |
|---|---|---|
.HEIC, .heif |
iPhone and iPad photos | Yes |
.png |
Screenshots, graphics | Yes, if the form wants JPG |
.webp |
Images saved from websites | Yes |
.tiff, .tif |
Scanners, print files | Yes |
.jpg, .jpeg |
Cameras, most apps | No: it already is JPEG |
Don’t just rename the file
Changing photo.heic to photo.jpg in Finder doesn’t convert anything. The file is still HEIC inside, and the website will either reject it or accept it and fail to show it. The image has to be re-saved as JPEG.
What changes in the JPG
- Transparency becomes a solid colour, white by default in FileMate. Logos meant for a coloured background may look boxed in.
- Size usually changes: PNG screenshots and TIFF scans become much smaller, HEIC photos slightly larger.
- Quality is 80% by default, which isn’t visibly different for photos. You can change it in FileMate Settings › Images & PDF.
