Yes. No signup, no premium tier, no daily cap on normal personal use. Display ads keep the site free.

Does it keep transparency?

Yes. Converting to PNG or WebP preserves the alpha channel. Converting to JPG flattens transparency to white.

Which format is best for the web?

WebP is usually 20-30% smaller than JPEG at the same quality and is supported in every modern browser.

Is the output watermarked?

No. The downloaded file is clean.

Does it work on phones?

Yes. The upload box accepts photos straight from the camera roll or the camera.

Free Image Format Converter — JPG, PNG, WebP

What does the image converter do?

The freeimgtool image converter changes one image format into another. Pick a JPG, PNG, or WebP from your device, choose the target format, and download the converted file. There is no signup, no email gate, and no watermark added to the result. The tool runs in the browser and on a small Python backend that uses the Pillow imaging library.

Each format exists for a reason. JPG is small and great for photos, but it does not support transparency. PNG is lossless and keeps transparency, which is why it dominates icons and screenshots. WebP is a modern format from Google that beats both on file size at the same quality, and many CMS templates now expect WebP for hero images. Converting between them is a daily task for anyone touching the web.

How to use it

Click the upload box and pick an image (up to 5 MB).
Choose the target format: JPG, PNG, or WebP.
If converting to JPG or WebP, adjust the quality slider to trade file size for sharpness.
Click Convert.
Click Download to save the result.

Why convert image formats

Common reasons people convert: shrinking a PNG screenshot to a JPG so it fits an email attachment limit, turning a transparent PNG logo into JPG with a white background for a print template, converting a JPG photo to WebP for a faster website, or pulling a WebP off the web that the rest of your software cannot open yet. One tool covers all of those.

Who uses it

Bloggers preparing images for upload to WordPress, Ghost, or Substack. Designers handing files to a printer that only accepts JPG. Developers shaving page weight by switching site images to WebP. Online sellers normalizing a mixed batch of product photos. Students fixing the "wrong file type" error in a classroom submission portal.

Frequently asked questions

Is this format converter free?

Yes. No signup, no premium tier, no daily cap on normal use. The site is supported by display ads.

What is the maximum upload size?

Five megabytes per file. If your source is larger, compress it first with the image compressor and then convert.

Will transparency be preserved?

Going to PNG or WebP keeps transparency. Going to JPG flattens transparent areas onto a white background because JPG cannot store an alpha channel.

JPG vs JPEG — what is the difference?

Nothing meaningful. JPG and JPEG are the same format with two filename conventions. This tool treats them as identical.

What does the quality slider do?

For JPG and WebP it controls the compression level. 100 is maximum sharpness with the largest file size. 70 is a good default for the web. PNG is lossless, so the slider is hidden.

Will I lose quality converting?

Going PNG to JPG or PNG to WebP is lossy — some detail is dropped to make the file smaller. Going JPG to PNG is technically lossless but the JPG compression artifacts are baked in and stay visible. WebP to PNG is lossless.

Is my image stored?

Uploads are kept only long enough to return a download link and are removed automatically. Privacy policy has the details.

Can I convert HEIC or AVIF?

Not yet. The current build supports JPG, PNG, and WebP. HEIC and AVIF are on the roadmap.
