Which format should I actually use?

For photographs on a website, WebP: well supported and much smaller than JPG. For anything that needs to open in old software, JPG. For logos, icons, and anything with a transparent background, PNG or WebP. AVIF is smaller still but support outside browsers is thin. If you are unsure, convert to WebP and keep the original.

Are my images uploaded anywhere?

No. Every part of the conversion runs inside your browser. Your images are never sent to us or anyone else, and you can confirm it by disconnecting from the internet once the page has loaded: the tool keeps working.

What happens to a transparent background?

It depends entirely on the destination. PNG, WebP, and AVIF all store transparency, so it comes through exactly as it was. JPEG cannot store it at all, so those pixels have to become a real color. You pick which one before converting, rather than finding a white or black box afterwards.

Why can I convert from HEIC but not to it?

Because writing HEIC needs a patent-encumbered encoder that browsers do not ship, and because nobody needs one: your iPhone already produces HEIC files. Reading them is the useful direction, and that is the direction that works here.

Can I convert an animated GIF?

No, and the tool says so rather than quietly doing the wrong thing. This kind of conversion reads a single frame, so an animation would come back as a still picture that looks fine and has lost its movement. We would rather refuse than hand you that.

Will converting make my file smaller?

Sometimes dramatically, sometimes not at all, and sometimes the opposite. Converting to a newer format like WebP usually shrinks things; converting to an older one for compatibility usually grows them. Rather than promise a figure, every file reports what it weighed before and after.

Does converting remove my photo's location data?

Usually, yes. Writing a new file drops the hidden metadata a camera or phone attaches, including GPS coordinates. That is often useful before sharing a photo publicly, but do not lean on it as a privacy tool. Check the file yourself if it matters.

How it works

Three steps to a different format

1
Add your images
Drag them in, paste from your clipboard, or browse your files. Mixed formats in one batch are fine: each file is read on its own terms.
2
Pick the format you need
Choose what to convert to, and what goes behind any transparency if the destination cannot store it. Quality is matched to your original unless you set it yourself.
3
Download
Save the converted files. Nothing was sent anywhere, so there is nothing to delete afterwards.

Why this one

Why convert here

It reads more formats than it writes

JPG, PNG, WebP, AVIF, BMP, GIF, and HEIC all go in. Four come out (JPG, PNG, WebP, and AVIF), because those are the four worth writing. Nobody needs a tool that produces new BMPs, and an iPhone already makes the HEICs.

02
Transparency is handled, not ignored
JPEG has no transparency channel, so converting a cut-out logo to JPG has to put something behind it. You choose the color rather than discovering it afterwards. Convert to PNG, WebP, or AVIF instead and the transparency comes through untouched.
03
It tells you when another format was better
Every conversion is measured, and if a format you did not ask for came out meaningfully smaller at the same visible quality, it is offered next to the file. You asked for a specific format and you get it, but you are not kept in the dark about the alternative.
04
Quality is measured, not guessed
For the lossy formats, the tool compares each result against your original and keeps a setting that still matches it closely, per image. A slider at “80” means something different for a screenshot than for a photograph, which is why the default is not a slider at all.
05
No limits, no queue
The work happens in your browser, so there is no server to wait for and nothing for us to ration. Run it as many times as you like.
06
A whole folder at once
Add as many files as you like. Each one is converted separately and gets its own result, so a file that cannot be read does not stop the rest of the batch.

Who it's for

When you'd use it

Someone with a mixed folder
Screenshots, phone photos, and downloads all in one place, all needing to end up as the same thing before they go anywhere.
Someone hitting an upload limit
A form that only accepts one format, or refuses anything over a few megabytes. Converting usually solves both at once.
Someone tidying up a website
Older JPGs and PNGs moved to WebP or AVIF, which is normally the largest single improvement available to a page's loading time.

Transparent Backgrounds: What PNG Does That JPG Can't

Your logo keeps arriving with a white box around it. Here is why that happens, which formats can actually hold emptiness, and what the grey checkerboard really means.

Remove the Background From a Product Photo

Marketplaces want the product on plain white or on nothing at all. Here is how to cut one out, which subjects come out cleanly, and the saving mistake that puts the background straight back.

WebP vs JPG vs PNG: Which Format to Use for What

WebP makes smaller files than JPG at the same visible quality, PNG is the only one of the three that keeps a transparent background, and JPG is the one every upload form and print shop accepts. Here is which to use for photos, logos, screenshots, and forms.
