Compression
80%

Lower quality gives smaller files. JPG and WebP become slightly less sharp; compression is lossy, so some detail is lost.

PNG works differently: quality sets how many colours are kept (up to 197 colours). At 100% PNG is saved losslessly and may not get smaller. For photos, JPG or WebP usually gives much smaller files.

Photo details stored inside the file (EXIF, such as camera model and GPS location) are removed from the new copies. Your original files are never changed.

    How to compress images online for free

    1. Choose your images. Tap Choose images or drag them onto the box. You can pick several JPG, PNG or WebP files at once.
    2. Pick a compression level. Balanced is a good start. Use Maximum compression for the smallest files, or High quality when detail matters most.
    3. Change format or size if you need to. Convert JPG to WebP, PNG to JPG and more, or resize to a custom size or a social media size.
    4. Press Compress & convert. Each image shows its new size and how much space you saved.
    5. Download. Save images one by one, or tap Download all to get them in a single ZIP file.

    Supported formats and conversions

    You can reduce the file size of JPG, PNG and WebP images, and convert between them: JPG to PNG, PNG to JPG, JPG to WebP, PNG to WebP, WebP to JPG and WebP to PNG. HEIC photos can be converted to JPG or PNG in browsers that can open them, such as Safari on iPhone, iPad and Mac.

    When you convert a transparent PNG or WebP to JPG, the see-through areas are filled with white, or with any background colour you choose.

    Choosing the right quality and format

    JPG is best for photos and works everywhere. WebP usually makes photos 25% to 35% smaller than JPG at similar quality and is supported by all modern browsers, which makes it a great choice for websites. PNG is best for logos, screenshots and graphics with sharp edges or transparency.

    For website images, a width of about 1200 to 2000 pixels is enough for most layouts. Resizing a 4000-pixel phone photo down to 1600 pixels often saves more space than any quality setting.

    Private by design: no uploading

    Most online compressors upload your photos to their servers. This free image compressor works differently. Everything happens on your phone, tablet or computer, using your browser’s own image tools. Your photos, their names and their details are never sent anywhere, and there is no account to create.

    Frequently asked questions

    Is this image compressor really free?

    Yes. There is no signup, no watermark, no daily limit and nothing to pay. You can compress as many images as your device can handle.

    Are my photos uploaded to a server?

    No. Your images are opened, compressed and converted inside your own browser. They are never sent to this website or to any other service, so the tool even keeps working if your connection drops after the page has loaded.

    How much smaller will my images get?

    It depends on the picture. Photos straight from a phone camera often shrink by 50% to 80% at the Balanced setting, and even more if you also resize them. Images that were already compressed may shrink very little. The tool shows the exact before and after size for every file.

    Will compression reduce quality?

    JPG and WebP compression is lossy, which means a little detail is removed to save space. At the Balanced (80%) and High quality settings the difference is usually hard to see on a phone or website. You can compare and try again with a higher quality if needed.

    Why did my PNG get bigger or barely smaller?

    PNG is a lossless format, so saving it at 100% keeps every pixel and may not reduce the size. Below 100%, the tool reduces the number of colours, which works very well for logos, screenshots and graphics. For photos, convert to JPG or WebP for much smaller files.

    What happens if the new file is larger than my original?

    This can happen with images that were already well compressed. The tool tells you clearly and gives you a button to keep the original file instead.

    Can I convert HEIC photos from my iPhone?

    Yes, in Safari on iPhone, iPad and Mac, which can open HEIC photos. Chrome and most Android and Windows browsers cannot open HEIC files. If yours cannot, set your iPhone camera to Most Compatible (Settings, Camera, Formats) or export the photo as JPG first.

    Why can't I choose WebP on my iPhone?

    Safari can display WebP images but cannot create them. Use Chrome, Edge, Firefox or Samsung Internet if you need WebP files.

    Does the tool keep my photo's EXIF data?

    No. The new copies do not include EXIF details such as the camera model, date or GPS location. This is good for privacy when you share photos online. Your original files are not changed.

    Can I compress many images at once?

    Yes. Select or drop several images, choose your settings once and press Compress & convert. Download each image separately or all of them together in one ZIP file.
