What is Convert format?
Convert format is a free tool in Pixelift that works online with no installation. Convert an image to JPG, PNG, WebP, AVIF or GIF and set the quality from 10 to 100%. The Pixelift server converts it with the Sharp library, no AI involved. Free, with no account and no credits. Engine: Sharp. No credits are charged per result. Files go to our server in the EU; if the tool uses an AI model, it runs at a provider from our subprocessor list. We never train models on them.
What you get
Quality slider 10–100%
Lower quality gives a smaller file. GIF has no quality setting.
Before and after comparison
A slider on the image shows the original and the result side by side, with the file size before and after below. If the file comes out larger than the original, the page says so.
Free, no account
Conversion uses no credits. The only limit is 20 conversions per 15 minutes.
When it helps
Lighter images for a website
Turn JPG or PNG into WebP or AVIF and compare the size before and after.
A file any program can open
Turn WebP or AVIF into JPG or PNG when older software or a website won't accept it.
Graphics with a transparent background
Save as PNG or WebP to keep transparency. JPG does not support it.
Output formats
- JPG: for photos; no transparency
- PNG: keeps transparency; colours reduced to a palette (up to 256), so photos may lose some colours
- WebP: usually a smaller file, with transparency
- AVIF: often the smallest file; older software may not open it
- GIF: up to 256 colours and only the first frame, no animation

Frequently asked questions
Is the converter free?
Yes. It uses no credits and works without an account; the only limit is 20 conversions per 15 minutes.
Which formats can I upload and get?
You can upload JPG, PNG, WebP, AVIF or GIF up to 20 MB and save the result as JPG, PNG, WebP, AVIF or GIF. iPhone HEIC and RAW files are not supported.
Is PNG lossless?
Not in this tool. Sharp saves PNG with a palette of up to 256 colours to keep the file small, so photos may lose some colours. Transparency is kept.
Will an animated GIF stay animated?
No. Only the first frame of an animated GIF is kept, including when converting to GIF.
What happens to my image?
It goes to the Pixelift server in Germany (EU), where the Sharp library converts it. It is not sent to any AI provider. Without an account we do not save the result; when you are signed in, the original and the result are saved in your account history.

No, one image at a time.
