About the image resizer
An image resizer changes an image to exact pixel dimensions — for thumbnails, social images, avatars or upload limits. This tool resizes with high-quality smoothing and preserves aspect ratio by default, exporting a lossless PNG, entirely in your browser.
Frequently asked questions
Is this tool free?
Yes — completely free, no signup, no watermark and no limits. Startup OG funds the site through its directory and partner program, not paywalled tools.
Is my file or data uploaded anywhere?
No. Everything runs locally in your browser — your file or text never leaves your device and nothing is stored on a server.
Does resizing an image reduce quality?
Scaling down is generally clean. Scaling up cannot add detail and will look soft — start from the largest original you have.
How do I resize an image without stretching it?
Keep "maintain aspect ratio" checked so width and height scale together. Unchecking it lets you set both independently, which can distort the image.
