How to Resize Images to Custom Dimensions

1Upload Images
Select one or more images you want to resize.
2Choose Dimensions or Preset
Enter custom width/height or pick standard presets (1080p, 4K, Instagram, YouTube).
3Select Fit Mode
Choose Cover (crop overflow), Contain (letterbox padding with color), or Stretch.
4Resize & Save
Download resized images individually or in a ZIP archive.

Lock Aspect Ratio: Keeps width and height proportional to prevent image distortion.
Fit Mode (Cover / Contain / Stretch): Handles aspect ratio mismatches with cropping or background padding.
Display Presets: Instant presets for Full HD, 4K, Instagram, and YouTube banners.

Aspect Ratio Locking
Maintains exact proportions automatically when adjusting width or height.
Social & Display Presets
One-click sizing for Full HD (1080p), 4K, Instagram (1:1, 4:5), YouTube, Twitter.
Smart Fit Modes
Choose Cover (crop overflow), Contain (letterbox padding), or Stretch.
Batch Processing
Resize multiple images simultaneously with identity-keyed file tracking.

Cover scales the image to completely fill the target dimensions, cropping any excess overflow. Contain scales the image so the entire photo is visible, adding customizable background padding to fill any letterbox margins.

No, and confusing the two is why people end up with files still too large. Resizing changes how many pixels the image contains; compressing changes how many bytes are spent describing each pixel. Resizing is by far the bigger lever — halving both dimensions removes three quarters of the pixels — and it is also the one with no visible cost provided you do not go below the size the image will be displayed at. Resize first; compress only if the result is still too big.

Yes, in one way that surprises people. For JPEG and WebP you have both levers, dimensions and quality. For PNG you effectively have only dimensions: PNG is lossless and the browser encoder ignores a quality setting for it entirely, so resizing is the whole mechanism. That is worth knowing before you spend time looking for a PNG quality slider that would not do anything.

Set the target box and pick the fit mode according to what matters more. Auto-Crop to Fill gives you a set of identically sized images with consistent framing, at the cost of trimming the edges of anything whose proportions differ — right for thumbnail grids and product listings. Add Blank Space keeps every photo complete and pads the difference, right when nothing may be cut. Avoid Stretch on a mixed batch: it forces every image to the same shape and visibly distorts the ones that did not match.
