Tips for resizing without losing quality
- Always lock aspect ratio — changing only width or height while keeping aspect ratio prevents distortion
- Resize down, not up — making images larger reduces quality. Always start with a high-resolution original
- Use PNG for logos and graphics — PNG preserves sharp edges better than JPG when resizing
- Compress after resizing — resize first, then compress to reduce file size

Can I resize an image to a specific KB size?
Yes — use the compress tool to target a specific file size in KB. Combine resize + compress for precise control over both dimensions and file size.
Does resizing an image change its quality?
Resizing smaller preserves quality well. Resizing larger (upscaling) reduces sharpness. For upscaling, use the AI upscale option when available.
Can I resize images on my phone?
Yes — Fourmeld Image Tools works in any mobile browser. Upload from your camera roll and download the resized image directly to your phone.
