Frequently Asked Questions

Why do I need a 128×128 pixel image?
128×128 pixels is the standard size for browser favicons, Discord custom emojis, Minecraft skins, and small app icons in notification trays. It is a power of 2, making it efficient for icon sets and sprite sheets.
Should I keep the aspect ratio locked or unlock it?
Keep it locked (default) if you want your image to fit within 128×128 without distortion — the tool will scale proportionally. Unlock it if you need to fill exactly 128×128, which may stretch the image.
Will resizing to a larger size reduce quality?
Enlarging an image beyond its original pixel count adds pixels by interpolation, which softens edges. For best results, always resize from an image that is already larger than the target. Downscaling always preserves quality.
Which format should I choose — JPG or PNG?
Use JPG for photographs and general images (smaller file, good quality). Use PNG for logos, icons, screenshots, or anything with text or sharp edges — PNG is lossless and supports transparency.
Is my image uploaded to a server?
No. All resizing happens locally in your browser using the HTML Canvas API. Your photo never leaves your device.
