Frequently asked questions
- Is Image Convert free to use?
- Yes. Image Convert is available on the free plan with 20 daily runs. Paid plans add higher quotas for repeat work.
- Which format should I pick for a photo?
- JPEG for photos, WebP when the file needs to be small for the web, PNG when transparency or sharp text matters. The pixels stay the same; the format is a choice about the destination.
- Does converting to JPEG lose quality?
- JPEG is lossy, so fine detail and hard edges degrade a little every time the file is written. Convert once from the original rather than re-saving a JPEG repeatedly.
- Will transparency survive the conversion?
- Only into formats that support it. JPEG has no alpha channel, so transparent areas are filled with a solid colour when a PNG is converted to JPEG.
- Does converting change the image dimensions?
- No. Format conversion rewrites how the pixels are encoded, not how many there are, so width and height come out unchanged.
