Any image format

Using the converter

Add one image. Drop it on the box above or click the box to pick a file. The box takes any image your browser can open. That includes JPG, PNG, WebP, GIF and BMP. If you drop several files, only the first one is used.
Choose the new format. The "Convert to" list has three choices: JPG, PNG and WebP. JPG is selected first.
Set the quality, if it matters. The slider goes from 10% to 100% and starts at 92%. It only changes JPG and WebP files. When you choose PNG, the slider turns off.
Click Convert & Download. The new file keeps your file name and gets the new ending. For example, logo.png becomes logo.jpg. A name with no ending, such as scan, becomes scan.jpg. Your original file is not changed. After the download, the tool shows the new file name and size.

JPG, PNG and WebP compared

The right format depends on what is in the picture and where it will be used. This table covers the three formats the tool can save.

Format	How it saves	Transparency	Quality slider	Good for	Not good for
JPG	Lossy: it drops some detail to make the file smaller	No. In this tool, clear areas become white	Yes	Photos, email attachments, older programs and upload forms	Logos, icons and screenshots with small text
PNG	Lossless: it keeps every pixel exactly	Yes	No effect, so it turns off	Screenshots, logos, icons, images you will edit again	Large photos. The file is often several times bigger than a JPG
WebP	Lossy, with the quality you choose	Yes	Yes	Images on your own website	Older software, and upload forms or email programs that do not accept it

All current browsers can show WebP. The problem is other software. Some upload forms, office programs and email programs still reject it. If you are not sure, JPG for photos and PNG for graphics are the safe choices.

What changes in the new file

The tool draws your image onto a hidden canvas at its full size. Then your browser saves that canvas in the new format. This is simple, and it has a few effects you should know about.

Width and height stay the same. A 3000 × 2000 image stays 3000 × 2000. To change the size, use Resize Image.
Transparent areas become white in a JPG. JPG cannot store transparency. So before it saves a JPG, the tool paints the canvas white and draws your image on top. Soft edges blend into that white too. A logo made for a dark website can get a thin light edge. PNG and WebP keep transparency.
Photo data is removed. The new file is built from pixels only. EXIF data such as the date, the camera model and the GPS location is not copied. That is useful before you share a photo in public.
Animation is lost. An animated GIF or WebP becomes one still image.
Colours can shift a little. The colour profile of the original file is not copied. Most images look the same. Some photos with a wide colour range, such as photos from recent phones, may look slightly less bright.

Converting does not add quality

A new format cannot bring back detail that is already gone. These cases come up often:

JPG to PNG. Any blur or small square blocks from the JPG stay in the PNG. The file also gets much larger, because PNG stores every pixel exactly. Do this only when a program asks for PNG, or when you will edit the image many times.
PNG photo to JPG. This is where conversion helps most. A photo saved as PNG usually becomes much smaller as a JPG.
JPG to WebP and back. Both are lossy, so each save throws away a little more detail. Converting back and forth adds up. Always start from the best original you have.
Screenshot to JPG. Text can get soft edges and faint marks around the letters. For screenshots, PNG is usually the better choice.

Picking a quality value

The default of 92% keeps almost all the detail. For photos on a website, 75–85% is a common range. Lower values give smaller files but add blur and blocks, mostly near sharp edges. Look at the result at full size before you use it.

Note that 100% is not lossless for JPG. It still makes a new lossy file, and that file can be bigger than the one you started with. Also, the same number can give different results in different browsers, because each browser uses its own encoder.

The tool shows the size of the new file after the download, not before. If you want to see the before and after size side by side, the Compress Image tool shows both, but it only saves JPG.

Common mistakes

Converting a transparent logo to JPG. It gets a white box around it. That looks fine on a white page and wrong on any other colour. Keep logos as PNG or WebP.
Converting the same file again and again. Go back to the original each time instead.
Converting to the same format. PNG to PNG gives a file with the same name as your original. Your browser will usually add a number such as (1) to the new file.

Limits

One image at a time. There is no batch mode.
Only three output formats: JPG, PNG and WebP. It cannot save GIF, AVIF, ICO or SVG. For an ICO file, use the Favicon Generator.
If your browser cannot open a file, a message says so, and nothing downloads. iPhone HEIC photos are a common example. Safari can usually open them, while many other browsers cannot.
Some browsers cannot create WebP files. They make a PNG instead. The tool then gives the file a .png ending and tells you, so you can try another browser for WebP.

Frequently Asked Questions

Which formats can I convert to and from?

You can add any image your browser can open, such as JPG, PNG, WebP, GIF or BMP. You can save it as JPG, PNG or WebP. The new file keeps your file name with the new ending, so photo.png becomes photo.jpg. A file name with no ending gets one added.

What happens to a transparent background when I convert to JPG?

JPG cannot store transparency. Before saving a JPG, the tool fills the canvas with white and draws your image on top, so transparent areas become white. If you need to keep transparency, choose PNG or WebP.

Does the Quality slider work for PNG?

No. The slider only changes JPG and WebP files. PNG is lossless, so it keeps every pixel and has no quality setting. When you choose PNG, the slider turns off and a short note says why. For JPG and WebP it goes from 10% to 100% and starts at 92%.

Will converting JPG to PNG improve the quality?

No. Detail that the JPG already lost cannot come back. The PNG will look the same as the JPG but will usually be much larger. Convert to PNG only when a program needs PNG or you plan to edit the image many times.

Does the converter keep EXIF data and animation?

No. The new file is made from the pixels only, so camera data such as the date, camera model and GPS location is removed. An animated GIF or WebP becomes a single still image.

Is my image uploaded to a server?

No. Your browser opens the image, draws it on a canvas and saves the new file on your device. Nothing is sent to FreeToolPoint or anyone else.
