JPG, PNG, WebP supported
compressed_ plus your original name, with a .jpg ending. For example, beach.png becomes compressed_beach.jpg.It helps to know exactly what happens, because it decides which images this tool is good for. Your browser opens the image, draws it onto a hidden canvas at its full size, and saves that canvas as a new JPEG file at the quality you chose. Four things follow from that:
.jpg back.The slider controls how much detail JPEG is allowed to throw away. Lower numbers give smaller files but add blur and small square blocks, most of all around sharp edges. There is no single right number. The best way is to try a value, look at the result at full size, and go lower until you start to notice a change. Then go back up one step.
These starting points work for most photos. Your own image may need a little more or less.
| Use case | Quality to start with | Before you compress |
|---|---|---|
| Large banner or hero image on a website | 75–85% | Resize to the widest size your page shows, often around 1600–2000 px. |
| Photo inside a blog post | 70–80% | Resize to your content column width, often 800–1200 px. |
| Email attachment or form upload with a size limit | 60–75% | A phone photo is often far larger than needed. Resize first, then compress. |
| Product photo for an online shop | 80–90% | Buyers zoom in, so keep more detail. A cut-out with a clear background gets a white background here. |
| Screenshot with small text | 85–95%, or do not use JPEG | Check the text after compressing. If it looks fuzzy, keep the original PNG. |
| Logo or icon with a clear background | Not a good fit | The clear areas will turn white. Keep it as PNG, or convert it to WebP. |
Two more notes on the number. First, 100% is not "no compression". It still makes a new JPEG, and that file is often larger than the photo you started with. Second, the number is not the same across apps. 80% here will not give the same file as "80" in a photo editor or on another website, because each program uses its own JPEG encoder.
Photos straight from a phone or camera are usually saved at high quality, so they often shrink a lot at 70–80%. But a JPEG that was already compressed by a website or a messaging app has little left to remove. Saving it again mostly adds more blur for a small gain. JPEG is lossy: each save throws away some detail, and you cannot get it back. Always compress from the best copy you have, not from a copy of a copy.
PNG is lossless. It keeps every pixel exactly. That makes it large for photos but very good for flat colours, sharp lines and text. So the result depends on what is in the picture. A photo saved as PNG usually gets much smaller as a JPEG. A simple graphic with a few flat colours may get only a little smaller, or even larger, and the edges can look soft. And as noted above, any transparent parts become white.
WebP files are often already well compressed. Turning one into a JPEG may save little or nothing. The main reason to do it is compatibility, for example when an older program or an upload form does not accept WebP. If you only want a smaller WebP file, this tool is not the right choice, because it cannot save as WebP.
If the Saved number is 0%, the new file came out the same size or larger. The tool then shows a warning under the result. This usually happens for one of these reasons:
In these cases, keep your original file. A smaller number in the Saved box is only a win if the image still looks right.
You can add JPG, PNG and WebP files, and most other image files your browser can open, such as GIF or BMP. The result is always a JPEG file. It is saved with the name compressed_ plus your original file name and a .jpg ending.
The transparent parts turn white. JPEG cannot store transparency, so the tool paints a white background before it draws your image. A note under the result tells you when your image had transparent parts. To keep them clear and still get a smaller file, save it as WebP with the Convert Image tool, or keep the PNG.
It means the new JPEG came out the same size as your file or larger. This is common for images under about 100 KB, for JPEGs that were already compressed, for simple graphics and screenshots, and at quality settings near 100%. In that case, keep your original file.
Yes. The tool draws your image onto a canvas and saves a new JPEG from the pixels only, so camera details such as the date, camera model and GPS location are not copied into the new file. This is useful before sharing a photo in public. If you need to keep that data, keep the original file.
No. The tool handles one image at a time, and if you drop several files it uses only the first one. It also keeps the original width and height. To reduce the dimensions, use the Resize Image tool first and then compress the result here.
No. The image is opened, compressed and saved by your own browser using the HTML canvas. The file is not sent to FreeToolPoint or anyone else. When you close or refresh the page, the image is gone from the tool.
