Compress & Crop Images

A photo straight from the camera often weighs several megabytes and slows down your website. Here you compress several images at once, choose a modern format and see immediately how much you save. In the second mode you crop images to the exact sizes for Instagram, LinkedIn, Facebook, YouTube and X. Your images never leave your device.

How the tool works

Drag one or more images into the field, for example JPG, PNG or WebP. Then choose whether you want to compress the images or crop them for social media. Processing happens entirely in your browser.

Compress: format and quality

Choose WebP, JPEG or PNG as output, and AVIF in browsers that support it. The quality slider determines how strongly the image is compressed. For photos on websites, WebP at a quality of around 75 to 80 is usually a very good balance.

Maximum width

Set the maximum width of an image, for example 1920 px for a large header image or 1200 px for images within the text. Smaller images are never enlarged, so they do not become blurry.

Savings and download

For each image you see the old and new file size and the percentage saved. Download individual images or all of them at once.

Crop for social media

Choose a format: Instagram post 4:5 (1080 × 1350), Instagram square (1080 × 1080), Story and Reels (1080 × 1920), LinkedIn post (1200 × 627), LinkedIn cover (1584 × 396), Facebook cover (1640 × 624), YouTube thumbnail (1280 × 720), X post (1600 × 900) or link preview for Open Graph (1200 × 630). Move and zoom the image within the fixed frame until the crop is right.

Safe zones and warnings

Safe zone hints show where the platform’s profile picture, buttons or controls will later sit on top of the image. If the source image is too small for the selected format, the tool warns you before a blurry result is created.

Why lightweight images make such a difference

On most websites, images account for the largest share of the data. An uncompressed header image of several megabytes noticeably delays page loading, especially on mobile. Google measures this with the Core Web Vitals, above all Largest Contentful Paint, and it feeds into how your page is rated.

Less data also means less electricity and less CO2 on every visit. Our Website Carbon Check shows how much your website causes per page view. Well-compressed images are almost always the easiest lever.

On social media, the first impression in the feed counts. An image in the right format is not cut off, faces and logos do not end up under the profile picture or buttons, and the platform does not have to scale it down itself. The result looks clean and professional.

When saving, the tool also removes metadata, including the GPS location that many phones write into photos without you noticing. This way you do not accidentally reveal where a picture was taken.

Frequently asked questions about compressing images

Which format should I choose for my website?

For photos, WebP is the safe choice: all current browsers support it and it is significantly smaller than JPEG. AVIF often saves even more, but is not handled equally well everywhere. PNG suits graphics with few colours or transparency; for photos it is usually too large.

How large may an image on a website be?

As a rule of thumb, a large header image should stay below 300 KB and images within the text below 150 KB. More important than the exact number is that the image is not saved wider than it is displayed.

Do I lose quality when compressing?

With sensible settings you will hardly see a difference on screen. If in doubt, compare two quality levels and take the smaller file you are still happy with. Keep the original anyway, as print needs the full resolution.

Why does the tool warn that my image is too small?

The source image has fewer pixels in the selected crop than the format requires. It would have to be scaled up and would look blurry. Choose a larger original or zoom in less.

Are location and camera data removed?

Yes. Metadata is not carried over when saving, including the GPS location, the date taken and the camera model. This protects your privacy and makes the file slightly smaller, too.

Do iPhone photos (HEIC) work too?

Yes. Safari opens HEIC by itself; in Chrome, Edge and Firefox the tool loads a decoder (about 1.5 MB) with the first HEIC image. The conversion also runs only in your browser, the result has the correct orientation and comes out as WebP, JPEG, PNG or AVIF.

Is my input stored?

No. The tool runs entirely in your browser. Your input and files are neither transferred to us nor to third parties, and they are not stored. More in our privacy policy.
