Frequently Asked Questions
Does resizing an image reduce its quality?
Resizing changes pixel dimensions only. Images with enough pixels look identical after downscaling; only severe upscaling softens them.
Can I keep the aspect ratio?
Yes — the Resize tool locks the ratio by default. Enter one side and the other adapts automatically.
What is the best file format for a resized image?
JPG for photos, PNG for graphics and transparency, WebP when you need the smallest size for the web.
Does the tool upload my images?
No — everything runs in your browser. Your images never leave your device.
How this tool works
Resizing changes an image's pixel dimensions — how many pixels wide and tall it is. It is the most common image task on the web because every platform has its own ideal size.
- Upload your photo and choose a target width, height or a preset (thumbnail, cover photo, avatar). The tool keeps the aspect ratio by default so nothing gets stretched or squashed.
- Everything is processed locally with the browser's canvas engine, which means your original never leaves your device and the result downloads instantly.
Why resize properly
Wrong sizes are the number one reason images get rejected: an upload to a store that resizes anyway, a cover photo that crops your face, an avatar that looks blurry because it was scaled down the wrong way.
Resizing also improves performance. A 5000px photo displayed in a 400px box wastes bandwidth and slows the page; shipping the right size is the single biggest speed win you can make before lunch.
Pro tip: For crisp images, resize down rather than up. If you must enlarge, do it in small steps and consider keeping 2x resolution for retina displays.
