The GoToolsX Image Resizer is a free online tool that changes the width and height of JPG, PNG and WebP images by pixels or percentage, with social media presets and batch processing, entirely in your browser.

- Enter only a width in Fit mode to scale by width and let the height follow.
- Avoid enlarging small images far beyond their size; they will look soft.
- Use WebP or JPG for photos and PNG for graphics.
- Resize first, then compress with the Image Compressor for the smallest files.

Frequently asked questions (FAQ)
Is the image resizer free?
Yes, it is completely free with no limits or watermark.
Do my images get uploaded?
No. Everything happens in your browser.
How do I resize without stretching?
Use Keep aspect ratio (fit inside) and enter a width or height. The other side is calculated automatically.
How do I get an exact size like 1080 x 1080?
Choose Fill and crop to exact size and enter both numbers, or tap a preset. The image is scaled and the edges are cropped.
Can I resize by percentage?
Yes. Choose By percentage and enter a value such as 50 to halve the dimensions.
Will resizing reduce quality?
Making an image smaller keeps it sharp. Enlarging it cannot add detail, so very large enlargements can look soft.
Can I resize multiple images?
Yes. Add up to 50 images and apply the same setting to all.
What formats can I save?
JPG, PNG and WebP, or the same format as the original.
