How to Resize an Image Online
FastEdit resizes images entirely in your browser. Use it to make photos smaller for email, crop assets to exact dimensions, or prepare images for websites and social platforms without uploading the original file anywhere.
Walkthrough
- 01
Open FastEdit
Go to fastedit.net. The editor runs in any modern browser with no installation.
- 02
Drop your image
Drag and drop a JPG, PNG, WebP, AVIF, HEIC, SVG, TIFF, BMP, or other supported image file.
- 03
Set the new dimensions
Enter the target width and height, or choose a preset. Keep aspect ratio locked unless you intentionally need a different shape.
- 04
Choose output format and quality
Keep the same format or convert while resizing. For web use, WebP or JPEG at quality 75-85 usually gives a small file with good quality.
- 05
Preview and export
Check the resized preview, then click Export. The resized file downloads directly to your device.
Small things worth checking
- Resize to the actual display size. A 4000px photo shown in an 800px container wastes bandwidth.
- Keep aspect ratio locked to avoid stretched faces, logos, and product photos.
- Use PNG or lossless WebP for screenshots and graphics with sharp text. Use JPEG or lossy WebP for photos.
- Batch resize multiple images when preparing a gallery, product catalog, or website asset folder.
