Image tools
Six tools for pictures in JPG, PNG and WebP format; the converter also reads AVIF, GIF, BMP and SVG and has its own pages for WebP to JPG and PNG to JPG. The pictures are processed on your device and are not uploaded to our servers.

Tools in this section
- Compress imagesMake JPG, PNG and WebP files smaller without uploading them. Set the quality, reduce PNG files to 256 colours or fewer, and download them as a ZIP.
- Compress to sizeCompress a JPG, PNG or WebP picture to 20 KB, 50 KB, 100 KB or any size you enter. The result never exceeds the target and is made in your browser.
- Resize imagesResize JPG, PNG and WebP images by percentage, to pixels, or to a print size in cm or inches at a DPI, and fit a fixed size without cropping.
- Convert imagesConvert AVIF, WebP, PNG, GIF, BMP, SVG and JPG images to JPG, PNG or WebP in your browser. Several files at once, no upload, download as ZIP.
- WebP to JPGConvert WebP images to JPG in your browser, many at once. Set the quality, choose a colour for transparent areas, and keep the first frame of animations.
- PNG to JPGConvert PNG images to JPG in your browser, many at once. Pick the colour that fills transparent areas and the JPG quality; no upload, ZIP download.
- Crop imageCut out a part of a JPG, PNG or WebP image, freely or with fixed proportions such as 1:1 or 16:9. Exact pixel values, no upload.
- Remove metadataSee the location, camera and date stored in JPG, PNG and WebP photos, then remove them without re-compressing the picture. Nothing is uploaded.
Which tool for which task
- The file is too large to send or upload: compress it, and reduce the longest side if the picture has more pixels than needed.
- A form accepts files only up to a fixed size, such as 100 KB: compress to a size in KB.
- A form asks for a certain pixel size: resize.
- A program does not accept the format: convert. For the two most common cases there are separate pages, WebP to JPG and PNG to JPG, which explain animations and transparent backgrounds.
- Only a part of the picture is wanted, or fixed proportions such as a square: crop.
- A photo should be shared without the place, time and camera it was taken with: remove metadata.
JPG, PNG and WebP compared
The three formats store pictures in different ways. The difference that matters most is whether detail is thrown away to save space (lossy) or every pixel is kept exactly (lossless).
| Format | Compression | Transparency | Typical use |
|---|---|---|---|
| JPG (JPEG) | Lossy | No | Photos |
| PNG | Lossless | Yes | Screenshots, drawings, logos, text |
| WebP | Lossy or lossless | Yes | Photos and graphics on web pages |
Lossy formats work well for photos, where small changes are not noticed. They work badly for sharp edges and text, where they leave visible smears. For a screenshot with text, PNG usually looks better and can even be smaller.
Current versions of the common browsers display all three formats. Some older programs and upload forms do not accept WebP.
Pixels, megapixels and file size
The pixel size of a picture is its width times its height. A photo of 4000 × 3000 pixels has 12 million pixels, or 12 megapixels. Halving the width and the height leaves a quarter of the pixels.
The file size depends on the number of pixels, on the format and quality, and on the content: fine detail needs more data than even areas. Reducing the pixel size is therefore often the most effective way to make a photo smaller.
While a picture is processed it is held in memory without compression, with 4 bytes per pixel. A picture of 50 megapixels needs about 200 MB that way, which is why the tools refuse larger ones.
What happens to metadata
Cameras and phones store extra information in a photo, for example the camera model, the time and often the GPS position. The tools write their results from the pixels only, so this information of the original is not copied into the result. Some browsers add a short technical header of their own with the pixel size and the colour space.
A rotation that the camera stored is applied before the picture is processed, so results are upright the way a gallery shows the original.
To remove the metadata without changing the picture at all, use the remove metadata tool: it leaves out the metadata blocks and copies the picture data unchanged. JPG to PDF with Original quality also leaves out the metadata of JPG pictures.
Frequently asked questions
- Which format should I use for photos?
- JPG is accepted almost everywhere. WebP usually gives smaller files at similar quality and is a good choice for web pages, provided that everyone who receives the file can open it.
- Which format should I use for screenshots and logos?
- PNG, because it keeps sharp edges and text exactly and supports transparency. WebP is an alternative when the file is used on a web page.
- Can I get lost quality back by converting to PNG?
- No. Detail that a lossy format removed is gone. Converting to PNG only stores the picture as it is now, without further loss and usually in a larger file.
- Can I process HEIC photos from an iPhone?
- No. The tools recognise HEIC files and refuse them with a message. On an iPhone, the camera saves JPG when Most Compatible is chosen under Settings, Camera, Formats.
- Is there a limit for the size of a picture?
- A picture may have up to 50 MB and 50 megapixels, and a written picture may be up to 16,383 pixels wide or high. Browsers on phones can draw less; on iPhone and iPad the limit is 4096 × 4096 pixels. The tools check what your browser can draw and report it.
