Resize Image
To resize an image, add your files (.jpg, .png, .webp, .bmp) below and press the button: they're processed on your own device and you download the result, with nothing uploaded. It's free, needs no account, and works with files up to 500MB.
Each image is scaled down to fit inside this box, keeping its proportions; smaller images are left at their size. The format stays the same (JPG and WebP saved at 92% quality).
About the Resize Image tool
You can resize an image entirely in your browser — no software to install, no file upload, and no account required. The conversion runs on the browser's own Canvas API directly on your device.
How to resize an image privately
Every step below runs on the browser's own Canvas API inside this browser tab. Your .jpg file is never uploaded to a server — there's no network request carrying it anywhere.
Add your image files
Drag and drop, or click to select, your files (.jpg, .png, .webp, .bmp). They're read straight from disk into browser memory — no upload step exists.
Resize locally
FreePrivateConvert does this with the browser's own Canvas API, entirely within this browser tab.
Download the result
Save your new files one by one or all together as a ZIP. They only ever existed in this tab's memory — closing the tab without downloading discards them completely.
Convert Image to Image with ffmpeg (command line)
Prefer the terminal? This page uses your browser's built-in image engine; the equivalent ffmpeg command is:
ffmpeg -i input.jpg -vf scale=1280:-1 output.jpg- -i input.jpg
- Your Image file.
- -vf scale=1280:-1
- Scale to 1280 pixels wide; -1 keeps the height in proportion.
- output.jpg
- The Image file to create. ffmpeg picks the container from this extension.
Example: 1280px wide, height in proportion. On this page you pick the size.
Don't have ffmpeg installed? You don't need it: use the converter at the top of this page. It runs this conversion on your own device, and your file is never uploaded.
FAQ
- Are my files uploaded anywhere?
- No. Your files are read and processed inside this browser tab and never leave your device. You can confirm it in your browser's developer tools: the Network tab shows no upload.
- Does it reduce quality when you resize an image?
- Resizing changes the pixel count, so a smaller image holds less detail by definition. The output keeps the input's format: PNG and BMP stay lossless, while JPG and WebP are re-encoded at 92% quality. Images are only ever scaled down, never enlarged.
- Is there a file size limit?
- Yes: 500MB per file, and you can add several files at once. There's no account and no limit on how many files you convert.
- What is the ffmpeg command to convert Image to Image?
- Run: ffmpeg -i input.jpg -vf scale=1280:-1 output.jpg. This page does the same conversion with your browser's built-in image engine, so you don't need to install ffmpeg. Example: 1280px wide, height in proportion. On this page you pick the size.
