Image Resizer
Resize images in your browser
Set exact pixel dimensions or scale by percentage, with aspect ratio protected by default.
Your image stays on your device. Processed locally in your browser. We never upload or store your file.
Choose how to resize
Predictable dimensions, no crop
- Exact width × height Pixels
Set precise output dimensions.
- Resize by percentage
Scale up or down from 1% to 800%.
- Aspect ratio stays locked
Fit inside is the default. Unlock only if you want to stretch.
Resize by pixels
Choose an exact width and height
Enter the output dimensions in pixels. Aspect ratio is locked by default, so changing one side updates the other and Fit inside keeps the complete image visible without cropping.
Resize by percentage
Scale both dimensions together
Use a quick percentage or enter a custom value from 1% to 800%. Percentage mode always preserves the image proportions.
Downscale and upscale
Smaller is sharper than artificially larger
FileIvy uses the browser’s high-quality image sampling. Downscaling prioritizes clarity. Upscaling is allowed, but enlarging an image cannot create new detail and may make it look softer. FileIvy does not use AI upscaling.
Formats and orientation
Keep the original image format
JPEG stays JPEG, PNG stays PNG with transparency, and still WebP stays WebP when the browser can encode it reliably. FileIvy applies browser-supported EXIF orientation consistently and never silently converts the file.
Privacy and common questions
Your image stays on your device
Selection, validation, preview, resizing, comparison, and download happen locally in this browser tab. Re-encoding normally removes EXIF and other metadata; when dimensions do not change and FileIvy keeps the original file, existing metadata may remain.
