Image resizing questions
How is the aspect ratio kept?
Enter either width or height. The other dimension is calculated from the current image or crop and rounded to whole pixels. Check the output dimensions. Images cannot be enlarged beyond the source.
What if I need centimetres or exact width and height?
Use the submission photo tool for two dimensions and crop positioning, or to calculate pixels from cm and PPI. The calculation does not set print size or embed the selected PPI in the file. Set submission dimensions or calculate cm
Does resizing also guarantee a KB size?
Pixel dimensions and file size are different. This page starts without a KB limit, so the output may be larger in bytes. Enable the size limit if needed. If the fixed dimensions cannot meet it, the tool reports failure.
Is it free? Do I need an account or an app?
Choosing an image, compressing it and downloading the result are all free. No account or app installation is needed. Your browser must support JavaScript and image processing.
Is my image stored on a server?
Your selected image is processed in this browser. We do not upload it or keep it in site storage. The original file is not changed. Downloaded files are saved on the device you choose. Saving settings stores only up to 5 KB, size and format combinations in this browser. You can remove them from the saved list.
Only with your analytics consent, Google Analytics 4 (GA4) measures referral sources, page views, interface language, image selection, compression success or failure, and download clicks. We do not send your image, filename, image contents, or entered size. Google may process analytics cookie identifiers and connection information such as browser, device, and approximate region. Ad personalization and Google signals are disabled. Your choice is remembered for six months, and analytics cookies for up to 180 days. You can decline or withdraw consent at any time through ‘Analytics settings’ in the footer. All photo features work without consent. See the Google Privacy Policy.
Loading the website requires a network connection. Our hosting provider, Cloudflare, may process connection information such as your IP address to deliver and protect the site. This is separate from processing your selected image. See the Cloudflare Privacy Policy.
On your first visit to the default address, the site uses the country estimated from your IP address to choose a language. To remember your manual choice, only its language code is saved in this browser’s local storage and a cookie (for one year), so future visits to the default address can open in that language. A URL that specifies a language always takes priority. Your image and filename are not sent during this process. You can change the language at any time in the language menu.
Can I resize several images?
Multiple-image mode supports common pixel and format settings. It also applies a KB limit to each image and processes up to 10 files. Returning to one image restores your previous single-image settings.
Which formats are supported? Can I use PNG?
Supports JPG, JPEG and still PNG, WebP and single-photo HEIC. Up to 10 files, 20MB (20,000,000 bytes) and 24MP per file, 100MB total. APNG, animated WebP, GIF, HEIC sequences, multi-photo HEIC and PDF are unsupported. Large photos may exceed device memory.
