Resize Images

Resize one image or a whole batch to the size you need. Enter pixels with the aspect ratio locked or unlocked, scale by percentage, or pick a preset for Instagram, TikTok, YouTube, X, Facebook or LinkedIn. Quality starts at 100%, and everything runs in your browser.

How to use it

  1. Choose images with the button, drag them in, or paste one with Ctrl+V.
  2. Pick a method: By size (px), By percentage, or Presets.
  3. If the new shape differs from your image, choose crop to fill, fit inside, or stretch.
  4. Choose the output format and quality; the default keeps the original format at 100%.
  5. Press Resize, then download each image or all of them as a ZIP.

Questions

Can I set both the width and the height?
Yes. With the ratio locked, each image keeps its proportions and fits inside the width and height you enter, and typing one value fills in the other. Unlock the ratio to make every image exactly that width and height.
What if my image is a different shape from the preset?
You choose how to handle it: crop to fill the whole frame, fit the whole image inside and fill the rest with a background color or transparency, or stretch it to the exact size.
Which presets are included?
Instagram square (1080×1080) and portrait (1080×1350), Instagram/TikTok story (1080×1920), YouTube thumbnail (1280×720), Full HD, 4K, X post and header, Facebook cover and LinkedIn banner.
Will resizing make my images blurry?
Large reductions are done in steps to keep edges smooth, and JPG and WebP quality starts at 100%. Enlarging cannot add detail, so when sizing by pixels with the ratio locked you can choose not to enlarge images that are already smaller.
Can I change the file format while resizing?
Yes. Keep the original format or save as JPG, PNG or WebP. Every resized file shows its new pixel size next to the original size.
