About Image Resizer
Solasu Image Resizer is a 100% free browser-based tool that lets you resize images on your computer or mobile device without uploading files to any server. Supporting JPG, PNG, and WebP formats, it provides 5 flexible modes: Long Edge, Width, Height, Exact Size, and Percentage. All processing runs privately within your browser, ensuring maximum privacy and security.
5 Flexible Resize Modes
For social media and blogs, the 'Long Edge' mode (presets like 800px, 1280px, 1920px) automatically scales whichever side is longest while preserving the natural aspect ratio, whether your photos are landscape or portrait.
When designing web graphics or specific banners, you can set custom Width, Height, or an unconstrained 'Exact Size'. You can also scale images by Percentage (25%, 50%, 75%, 100%) for proportional resizing.
Smart Upscale Protection & Format Support
The 'Do not enlarge small images (No Upscale)' option is enabled by default to prevent smaller images from becoming blurry or pixelated.
Output format defaults to 'Keep Original', ensuring PNG transparency is preserved and JPGs remain JPGs. You can also explicitly convert between JPG, PNG, and WebP, and adjust quality or background color as needed.
Sequential Batch Processing & ZIP Download
Add multiple images at once via drag-and-drop. Images are processed sequentially in a background Web Worker, keeping your browser responsive even with large photo batches.
Once complete, download individual images or grab all resized files in a single ZIP archive. You can cancel active batch processing at any time.
Frequently Asked Questions
Can I resize images online for free?
Yes. You can resize JPG, PNG, and WebP images directly in your browser with high visual quality. No registration, install, or subscription required.
Can I change only the width of an image?
Yes. Select 'Width' mode and enter your desired width in pixels. With 'Keep aspect ratio' enabled, the height is automatically calculated to prevent distortion.
Can I change only the height of an image?
Yes. Select 'Height' mode and enter your desired height in pixels. With 'Keep aspect ratio' enabled, the width is automatically calculated.
Can I resize by specifying the long edge?
Yes. In the default 'Long Edge' mode, the longer dimension of each image is scaled to your target size while preserving proportions. Quick presets (800px, 1280px, 1920px) are available.
Can I batch resize multiple images at once?
Yes. Drag and drop multiple photos into the upload area. All files will be resized using your chosen settings and can be downloaded individually or as a single ZIP archive.
Can I convert formats to JPG, PNG, or WebP?
Yes. While the tool keeps your original format by default, you can open 'Advanced Settings' and choose JPG, PNG, or WebP to convert formats during resize.
Can I adjust the image quality?
Yes. For JPG and WebP outputs, you can adjust the quality slider from 1 to 100 (default 85) in Advanced Settings. PNG is lossless, so quality adjustment is disabled.
Can I enlarge smaller images?
By default, 'Do not enlarge small images (No Upscale)' prevents upscaling to avoid blurriness. You can uncheck this option if you want smaller images to be enlarged to the target dimensions.
Can I preserve the aspect ratio?
Yes. Aspect ratio is preserved by default across Long Edge, Width, Height, and Percentage modes. In Exact Size mode, aspect ratio is unlocked so you can set custom width and height independently.
What happens to GPS and EXIF metadata?
Input metadata such as GPS location and camera EXIF data are not transferred to the resized output. The canvas re-encoding strips metadata, and EXIF orientation is normalized so images display right-side up.
Are my images uploaded to any server?
No. All image decoding, resizing, and encoding take place entirely inside your browser (via Web Worker and Canvas). Your files never leave your device.
Where are resized images saved?
When you click Download or 'Download All as ZIP', files are saved directly to your device's default download folder. Nothing is stored in the cloud.
