RESIZE & CROP STUDIO
RESIZED OUTPUTS
Add one or more images above or load the sample image to begin.
Method and assumptions
Target dimensions are computed from either an explicit pixel width and height or a percentage scale factor. In Cover mode, the source aspect ratio is compared against the target aspect ratio and cropped around the chosen anchor (center, top, bottom, left, or right) so the image fills the exact frame without distortion. In Fit Inside mode, dimensions are scaled proportionally within the bounding box. In Contain mode, the image is letterboxed inside the exact target dimensions using the specified padding color.
Common mistakes and edge cases
Upscaling low-resolution images increases pixel dimensions and file size but does not invent new optical detail. Canvas outputs exceeding 16.7 megapixels are proportionally clamped to stay within mobile browser memory limits.
How to use
- Drop one or more images into the resizer studio.
- Choose a social preset (Instagram 1:1, 4:5, Story 9:16, YouTube 16:9, OpenGraph, X, LinkedIn) or enter custom width and height.
- Select Cover (crop to fill), Fit Inside (proportional max bounds), Contain (letterbox), or Stretch.
- Click Apply resize / crop and download your resized images individually or as a ZIP.
Example
Select the 1080×1080 Instagram Square preset with Cover mode and Center anchor on a 1920×1080 landscape banner: the tool crops the central 1080×1080 square and exports a crisp 1080×1080 image.
Frequently asked questions
- What is the difference between Cover and Fit Inside?
- Cover crops the image around your chosen anchor so the output matches the exact target width and height without distortion. Fit Inside scales the image proportionally so neither dimension exceeds your target box.
- Can I convert formats while resizing?
- Yes. Choose WebP, JPEG, PNG, or AVIF in the Export format selector to resize and transcode in a single pass.
