How to use this image converter
- Click the Choose Files button and select the images you want to convert.
- Set the Output format for each file, then click the gear if you want to adjust quality or size.
- Click Convert, then hit Download on each file or grab everything as a ZIP.
Convert any image
JPG, PNG, WebP, AVIF, GIF, BMP, TIFF, ICO and PDF output, with per-file control so you can send different images to different formats in one batch.
Keep the quality
Adjust quality per file and resize on the way through. Formats without transparency get a clean white matte instead of the black edges most converters leave behind.
Nothing is uploaded
Your files are read and written by your own browser. They are never sent to a server, so there is nothing to delete afterwards and no size or file-count limit.
More image tools
Everything below is built into this converter — no separate tool needed.
- Compress without converting — pick the same format as your input and lower the quality slider to shrink a file while keeping its type.
- Resize — open the gear on any file and set a maximum width; the height follows automatically.
- Images to PDF — choose PDF as the output to turn a photo or scan into a document.
- Make a favicon — choose ICO as the output to produce a browser icon from any square image.
What is an image file format?
An image format is the set of rules describing how the picture is stored on disk — how the pixels are laid out, whether they are compressed, and what extra information travels with them.
Lossy formats such as JPG and AVIF discard detail the eye is unlikely to notice in exchange for a much smaller file. Lossless formats such as PNG keep every pixel exactly, which matters for logos, screenshots and anything with sharp edges or text. WebP can do either.
The other difference that trips people up is transparency. PNG, WebP, AVIF and GIF can store transparent pixels; JPG cannot. Converting a transparent PNG to JPG will fill those areas — this tool uses white rather than the black most converters default to.

Frequently asked questions
Are my images uploaded to a server?
No. Conversion happens inside your browser using the Canvas API. Nothing is transmitted, stored or logged. You can disconnect from the internet after the page loads and it will still work.
Is there a file size or file count limit?
No. Most converters cap you at 1 GB or 20 files because they pay for server processing. There is no server here, so there is no cap. Very large images may simply take a moment on slower devices.
Which output format should I choose?
WebP is the best default for the web — typically 25–35% smaller than JPG at matching quality, with support in every modern browser. AVIF is smaller still. JPG is the most universally compatible. PNG is for transparency and flat graphics.
What happens to transparency when I convert to JPG?
JPG cannot store transparent pixels, so anything transparent has to be filled with a solid colour. This tool fills with white, which is what most people expect. If you need to keep transparency, convert to PNG, WebP or AVIF instead.
Why are some formats greyed out?
Browsers can read many formats but can only write a limited set. EPS, PSD, SVG and TGA would need server-side processing, which would mean uploading your files. We chose privacy instead.
Is JPG the same as JPEG?
Yes, identical. The two names exist only because older systems limited file extensions to three characters.
