Dimensions are best when an upload rule specifies an exact width and height in pixels.
Percentage is best for making an image proportionally smaller or larger.
Bulk resize applies the same dimensions, format, and target KB to many files.
Image Resizing Tools for Pixels, Scale, and Batch Workflows
Image requirements are not always expressed in the same way. A form may request 800×800 pixels, a website may ask for images reduced by half, and a content workflow may need an entire folder resized with identical settings. This hub keeps those workflows separate so you can choose the tool that matches the requirement.
If the only requirement is a strict file size, use the main Photo Resizer in KB or the Image Compressor. For a common upload limit, use the dedicated 20KB photo resizer, 50KB photo resizer, 100KB photo resizer, 200KB photo resizer, or 500KB photo resizer. To remove unwanted edges before resizing, start with Crop Image.
Tested as an image resizer collection
I test custom dimensions, percentage scaling, mixed-orientation batches, JPG, PNG, and WebP output, target-KB compression, individual downloads, ZIP creation, and private browser processing before publishing. Built and tested by Mozammel Hoshen Chowdhury. Review process: Editorial Policy.
Private by default
These image resizer tools are designed to process files locally in your browser. Personal photos, documents, and form images do not need to be uploaded to our server during normal resizing.
