A site says "file type not supported." Or your photo is 12 MB and won't send.
Pick the wrong format and logos turn blurry, files balloon, or the image won't open at all. You usually find out after the upload fails.
The fix is simple: pick the format by the job. Here is the short answer.
Quick answer
| Format | Use it for |
|---|---|
| JPG | Photos and everyday sharing |
| PNG | Logos, screenshots and anything with a see-through background |
| WebP | Websites |
| AVIF | Websites where every kilobyte counts |
| TIFF | Print and professional editing |
| HEIC | iPhone photos. Convert to JPG to share them |
Three rules that cover most cases
- Photo to share or upload? Use JPG.
- Logo, screenshot or see-through background? Use PNG.
- iPhone photo that won't open? Convert the HEIC to JPG.
Mistakes to avoid
- Saving a photo as PNG. The file gets several times bigger for no visible gain.
- Saving a logo as JPG. Edges blur and transparency is lost.
- Converting a JPG again and again. Quality drops a little each time, so keep the original.
Need to convert?
Drop your file, click Convert, download the result. It runs in your browser, so nothing is uploaded.
Decide the job first. Then pick the format.
