What is Free Image Resizer?
Resizing is averaging: turning source pixels into new target dimensions without quality loss. This browser-based resizer decodes 11 input formats — including iPhone HEIC and scanner TIFF — resamples with precision in linear light, and exports clean PNG, JPG or WebP directly inside your browser tab.
Batch Resize WorkflowAny preset or custom size
Drop photos in, pick Crop to fill or Fit, and each file is resampled to exact pixel dimensions locally — then downloaded individually or as a single ZIP.
How to use the free image resizer
Our online image resizer makes it effortless to prepare visuals for social media and web publishing without heavy software.

Review and download
Choose Crop to fill or Fit, select PNG, JPG or WebP, then download resized images individually or as a single ZIP.
Crop to fill or Fit (pad)?
Crop to fill
Fills every pixel at the selected ratio. The image resizer uses a centered crop, ensuring edge-to-edge coverage.
Fit (pad)
Keeps the complete image inside the canvas. The image resizer adds clean padding when aspect ratios differ.
What the image resizer controls
- Pixel dimensions: the image resizer outputs exact target widths and heights for crisp display.
- Aspect ratio: determines whether the image resizer crops to fill or pads the frame.
- Output format: export as PNG to retain transparency or JPG for compact file sizes.
A private, in-browser image resizer

Image resizer and preset FAQ
Is this image resizer free to use?
Yes, this online image resizer is 100% free with no limits, watermarks, or account registration required. You can resize unlimited single images or batches directly in your browser.
Does this image resizer crop my image?
Crop to fill uses a centered crop so the canvas is filled at the exact preset dimensions. Choose Fit (pad) when you need the image resizer to preserve the full image without cropping.
Can I resize several photos at once with this batch image resizer?
Yes. As a batch image resizer, you can add multiple browser-supported images at once, apply your target preset dimensions, and download individual files or a single ZIP archive.
Why use a browser-based image resizer instead of uploading to a server?
A browser-based image resizer keeps your photos completely private on your own device. Because images are processed locally using Canvas API, the image resizer is fast, secure, and does not upload your files to any remote server.
Should I choose PNG or JPG when using the image resizer?
PNG preserves transparency and is ideal for graphics and logos. JPG is usually smaller for photos, but transparent areas are placed on white because JPEG has no alpha channel.
Are these image dimensions official for every platform?
The source section identifies dimensions checked against stable first-party platform documentation. Other entries are practical presets verified to work reliably across modern screens.
