How to compress images

  1. 1

    Choose your images

    Pick photos or screenshots from your library, or drop files onto the page. Add as many as you need.

  2. 2

    Pick a size limit

    The default is 200 KB. You can switch to 500 KB, 1 MB, a number of your own, or no limit at all.

  3. 3

    Save the results

    On iPhone, tap Save to Photos and choose Save Images. On a computer, download everything as one ZIP file.

Why the text stays readable

Resolution comes first

At a fixed file size, text is much easier to read with more pixels at a slightly lower quality than with fewer pixels at a high one. The compressor finds the largest resolution that fits your limit, then spends what is left of the budget on quality.

Screenshots keep every pixel

PNG screenshots are compressed by reducing the number of colours instead of shrinking the picture, so letters stay pixel-sharp. Shrinking a screenshot would blur the text and often make the file bigger.

Full-resolution colour when there is room

When the size limit allows it, JPEGs are saved without chroma subsampling (4:4:4), which keeps coloured text and thin lines from smearing.

You can check before saving

Tap any result to switch between the original and the compressed version, and zoom in on the details that matter.

Supported formats

  • Input: JPG, PNG and WebP. Photos picked from the iPhone library are handed over by iOS as JPG, including HEIC originals.
  • Output: by default each image keeps its format. A PNG that is too photographic to fit the limit as a PNG is saved as a JPG, because that keeps far more detail. You can also force JPG, PNG or WebP.
  • Transparency is kept in PNG and WebP. Converting to JPG puts the image on a white background.

Frequently asked questions

Are my images uploaded to a server?

No. Compression runs in your browser using WebAssembly. Your images never leave your device, and the tool keeps working without a connection once the page has loaded.

Will the text in my screenshots or documents become blurry?

The compressor is tuned to prevent that. It keeps as many pixels as the size limit allows and reduces colours or quality before it reduces resolution. Open any result to compare it with the original before you save.

Why did the pixel dimensions of my photo change?

A 12 or 24 megapixel photo cannot fit in 200 KB at full size. The compressor picks the largest dimensions that fit and shows them next to the result. Choose a larger limit, or No limit, to keep more pixels.

How do I save all the images to Photos on iPhone?

Tap Save to Photos, then choose Save Images in the share sheet. All compressed images are added to your library at once. You can also download them as a ZIP file to the Files app.

Is location data removed from my photos?

Yes for every image that is re-encoded: the result contains no EXIF data, so no GPS position, camera model or capture time. If an image is already small enough that it is kept exactly as it was, its metadata is left untouched.

Is there a limit on the number or size of images?

There is no fixed limit. Images are processed one after another, so large batches work, but very large photos need a lot of memory on older phones.
