Reduce or increase image resolution
Prepare a photo for a website, listing or message. Set a width such as 1200 pixels; height follows the aspect ratio. The whole image is kept and output dimensions appear before download.
Reducing resolution removes detail; enlarging can reduce sharpness. File size is different from resolution. To set a size in KB, use image compression. To trim edges or make a square without distortion, open image cropping. Other formats are available in tool catalog.
Questions and answers
How do I resize a photo in pixels?
Choose JPG, PNG, WEBP or AVIF, set width or height and click Resize. With Keep aspect ratio enabled, the other dimension is calculated. Download the result or upload it to get a link.
How do I resize a photo by percentage?
Choose Percentage. A value of 50% halves both width and height. Exact output dimensions are shown before processing.
Can I set an exact width and height?
Yes. Turn off Keep aspect ratio and set both dimensions. A changed ratio stretches the image. Use cropping to change shape without distortion.
How does resizing differ from compression?
This tool changes pixel dimensions. For a file under 200 KB or 1 MB, use compression. File size after resizing depends on the image and output format.
Can I enlarge a photo without losing quality?
You can increase resolution, but no new detail is created and the image may become blurry. This is standard resizing, without AI enhancement. JPG and WEBP use 95% quality; PNG is lossless.
Which formats and limits are supported?
One JPG, PNG, WEBP or AVIF up to 50 MB, 24 MP and 12,000 pixels per side. PNG and WEBP preserve transparency; JPG makes it white. Animation and metadata are not retained.
Where is the photo sent?
Resizing runs in your browser. Unsupported AVIF is temporarily converted on the server. Only clicking Upload and get a link uploads a result up to 20 MB. Download local results before closing the page.
