How to resize image files in 3 steps
- Add your images by dragging them in or clicking the box.
- Open More options and set a maximum width, a maximum height, or pick a quick size.
- Download each resized image, or all of them together as a ZIP.
How this tool lets you resize image dimensions
Set a maximum width, a maximum height, or both. The picture is scaled to fit inside those limits and the aspect ratio is kept, so it never looks stretched. Images are never enlarged, because enlarging makes them blurry. You can also pick a quick size such as 1920, 1280 or 1080 pixels wide, and resize up to 30 images at once.
Common sizes when you resize image files
- 1920 px wide: full HD screens and large website banners.
- 1280 x 720 px: video thumbnails.
- 1200 x 630 px: link preview images for social sharing.
- 1080 px wide: social media posts.
- 800 px wide: blog post images.
Platforms change their recommendations, so check the current guidance before you publish.
Resize and compress together
Smaller dimensions already reduce the file size. For websites, resize first and then set a target size to get the fastest-loading result. You can do both on the same page, or use the dedicated compress image page for exact limits such as 100 KB.
Tips to resize image files cleanly
- Start from the largest original you have, because shrinking keeps detail better than enlarging.
- Keep the aspect ratio so people and objects do not look stretched.
- Use JPG or WebP for photos and PNG for graphics. See the image file type guide from MDN.
- Crop first if only part of the picture matters. The crop image page keeps the centre.
- Keep a copy of the original file.
Common problems and fixes
- The picture did not get bigger: the tool never enlarges images, so choose a larger original instead.
- The download button does not appear: the file may be damaged or in a format your browser cannot read. Try opening it in an image viewer first.
- The result looks too soft: raise the quality slider, because lower values trade sharpness for a smaller file.
- The colours look slightly different: some browsers convert colour profiles. Check the image in the app where you plan to use it.
- A large photo feels slow: your own device does the work, so close other tabs or lower the maximum width.
Frequently asked questions
How do I resize image files online?
Add your pictures, open More options and set a maximum width or height, then download the results.
Does resizing reduce image quality?
Making an image smaller keeps it sharp. The tool does not enlarge images, because that would blur them.
Will my image be stretched?
No. The aspect ratio is always kept. If you set both width and height, the image fits inside that box.
What size should website images be?
Most blog images look good at 800 to 1600 px wide. Resize first, then compress for fast loading.
Are my images uploaded to a server?
No. Everything happens inside your browser on your own device, so your files stay private.
Is this tool free?
Yes. It is free to use, with no sign-up and no watermark.
