Frequently asked questions
What happens to transparency when converting to JPEG? ›
JPEG has no transparency channel, so transparent areas are filled with the background color you choose before conversion.
Which format should I use? ›
JPEG for photos, PNG when you need transparency or lossless quality, WebP for a good balance of both at a smaller size.
Is the file uploaded during conversion? ›
No, conversion happens locally using the Canvas API.
Troubleshooting
Why does my converted JPEG have a black or white background instead of transparency? ›
JPEG cannot store transparency, so any transparent area is filled with the background color you selected before converting. Choose PNG or WebP if you need to keep transparency.
Why is the converted file larger than the original? ›
Converting a JPEG to PNG (or a highly compressed source to a higher quality setting) can increase file size, since PNG is lossless and JPEG/WebP quality is under your control.
