Resize and crop any image right in your browser. Set an exact width and height, keep the aspect ratio locked, or start from a ready-made size for social media or a passport photo. Choose whether the image is cropped to fill, fitted with padding, or stretched, then download it as PNG, JPG or WebP. Your photo never leaves your device — nothing is uploaded.
How to use
- Drop an image onto the box, or click to choose one.
- Enter a width and height, or pick a preset. Keep the lock on to preserve the aspect ratio.
- Choose how it fits (crop, fit or stretch) and the output format and quality.
- Check the preview and download — the original file is never changed.
Crop, fit or stretch
When the target size has a different shape than your image, the fit mode decides what happens. Crop fills the whole frame and trims the overflow. Fit keeps the entire image and adds padding around it. Stretch forces the image to the exact size, which can distort it.
Features
Ready-made size presets
One click sets the exact dimensions for Instagram, an X/Twitter header, an Open Graph image, a YouTube thumbnail, a passport photo and more.
Aspect-ratio lock
Lock the ratio so changing the width updates the height automatically and your image never looks squished.
Crop, fit or stretch
Decide exactly how the image fills the target size, with a background color for padded results.
Choose the output format
Export as PNG for transparency, or JPG and WebP with an adjustable quality slider to control file size.
Private by design
All resizing happens locally with the Canvas API. Your image is never uploaded to a server.
Common use cases
Social media posts
Hit the exact pixel size that Instagram, X or YouTube expect so your image isn't cropped awkwardly.
ID & passport photos
Resize and crop a photo to a required size before printing or uploading to a form.
Thumbnails & OG images
Make crisp thumbnails or share images at the right dimensions for websites and link previews.
Smaller files for email
Shrink large photos to reasonable dimensions so they attach and send quickly.
Notes & tips
- Enlarging an image beyond its original size reduces sharpness; resizing down keeps quality best.
- Crop mode trims the edges to fill the frame, so important details may be cut off — center your subject.
- Your original file is never modified; the tool always saves a new image.
- Everything runs on your device — no upload, no sign-up.
Frequently asked questions
- Is my image uploaded to a server?
- No. The resizer uses your browser's Canvas API to process the image locally. Your photo never leaves your device.
- How do I keep the aspect ratio?
- Turn on the aspect-ratio lock. Then changing the width updates the height automatically (and vice versa) so the image isn't distorted.
- What's the difference between crop and fit?
- Crop fills the entire target size and trims any overflow. Fit keeps the whole image and adds padding around it to reach the exact size.
- Will enlarging an image look blurry?
- Making an image larger than its original pixels can soften it, since there's no extra detail to add. Resizing down looks sharp.
- Which formats can I export?
- You can download as PNG (with transparency), JPG, or WebP, with a quality slider for JPG and WebP to balance size and clarity.
