Why use this tool?
Your image never leaves your device — everything is processed locally in your browser, so it stays completely private. Resizing helps you meet upload limits, fit images into documents, or create smaller versions for the web.
Frequently asked questions
Can I resize without stretching?
Yes — keep 'Lock aspect ratio' enabled and the other dimension updates automatically.
Does resizing reduce file size?
Smaller dimensions usually mean a smaller file. Combine it with Compress for the smallest result.
Is there a size limit?
No artificial limits — it's bound only by your device's memory.
