Nostr Photo Resizer

No. They are practical working canvases, not a complete official specification for every placement or account. Platforms change formats and crop previews differently. Check the linked official guidance and the actual upload screen.

Create an image that remains understandable when linked from different clients. Nostr media hosting is separate from this local resizer; review the host's retention and privacy terms before uploading.

The utility processes its text or image inputs in your browser. It does not submit them to a generation API, connect a social account, or publish the result. You choose when to copy, download, or share the output.

Try an independently hosted creator guide, with this specific detail: include a stable source URL and a plain-text summary. Replace the example with your own accurate information, then adapt the result to the field and audience you actually use.

Fit keeps the whole source image inside the canvas and fills unused space with the chosen background. Crop to fill covers the canvas without stretching but removes material near the edges. Compare both previews, especially when the source contains faces, small text, or a logo close to a border.

PNG is useful for crisp graphics and transparency; JPEG is often practical for photos; WebP can produce a smaller image where the destination supports it. Check the actual upload field before choosing. This utility offers PNG, JPEG, and WebP exports, but it cannot guarantee a platform accepts every format or size.

Choose a real PNG, JPEG, or WebP source and check the file and dimension limits shown by the tool. Renaming a file does not convert its format. If the output looks soft, start from a higher-resolution original or use a smaller canvas; enlarging an image cannot recover detail that was not present.

The tool resizes and crops; it does not remove backgrounds, reconstruct detail, or guarantee acceptance by every platform. Very large or unsupported files must be converted or reduced first. Review the relevant official references below and confirm the final result in the destination app.
