Control image size, ratio, and framing
The Resizer changes width, height, scale, and framing locally. Use it to reduce large batches, create required formats, and fine-tune an image with precise crop, borders, sharpening, and before/after comparison.
How to use it
- Import files and select the full batch or only images that need the rule.
- Choose exact dimensions, percentage scale, longest side, or maximum limits. Keep proportions to avoid distortion.
- Choose Fit, Fill and crop, or Padding. Open the editor to correct framing for any image.
- Compare, process, and export with the needed format and naming pattern.
What the Resizer does
It changes image geometry: width, height, percentage, aspect ratio, and visible area. Unlike the Compressor, its focus is final resolution and framing. Reduce web photos, standardize product images, create squares for social media, constrain oversized files, or enlarge only when necessary.
- Exact dimensions set a specific width and height.
- Percentage scale is useful for 25%, 50%, 150%, 200%, and other values.
- Maximum limits reduce only images above the selected width, height, or longest side.
- Prevent upscaling avoids unnecessary enlargement.
Aspect ratio, fit, and crop
Keeping aspect ratio prevents people, products, and text from stretching. Fit keeps the whole image inside the target and may leave space. Fill and crop covers the target and may remove outer areas. Padding preserves the image and fills leftover space with a chosen color.
- Use Fit for catalogs and content that cannot lose area.
- Use Fill and crop for covers, avatars, thumbnails, and mandatory dimensions.
- Use Padding to standardize products or logos without cutting them.
- Manual, centered, smart, and focal-point modes decide what stays in the crop.
Individual editor, gallery, and quality
In the editor, the frame is exactly the exported area. Move and resize the crop, lock ratio, use guides, keyboard, undo, and apply to the selection. Changes remain non-destructive until export. Horizontal gallery, grid, and focus mode retain files and selection. Fast uses a lighter path, Normal balances, and Maximum Quality uses more careful resampling. Native Canvas, Pica MKS 2013, and Lanczos 3 are available in advanced settings.
- Rounding controls how calculated values become final pixels.
- Sharpening, denoise, brightness, contrast, and saturation are optional conventional adjustments.
- Uniform border removal suggests a crop; inspect the preview to keep legitimate content.
Local AI, uses, and export
AI is optional and runs only with locally installed models. Test one image and compare before using a batch; it can alter details, so it is not ideal for text, documents, trademarks, or evidence requiring literal fidelity. Use this tool for website photos, standardized products, banners, covers, thumbnails, square posts, and platform limits. Use the Compressor for weight only. Choose format, names, suffixes, and numbering, inspect names, and export one item, selection, batch, or ZIP. Saving to a folder depends on the browser; processing remains local.
Frequently asked questions
What is the difference between resizing and AI upscaling?
Resizing changes width and height. AI Upscaler attempts to rebuild detail while enlarging an image.
Can I set only width or height?
Yes. With aspect ratio preserved, the other dimension is calculated automatically.
Why was my image cropped?
This happens when the destination format must be filled and the original aspect ratio does not match. Review framing in the preview.
What are maximum limits?
They are dimensions an image should not exceed. Larger files are reduced while preserving aspect ratio.
Can I resize multiple images?
Yes. Add a batch, test the configuration on one image, then apply it to all files or selected items.
Which output format should I use?
Use PNG for transparency and graphics, JPG for photos, and WebP when the destination supports it and you want a smaller file.
