About this tool
This free online image resizer lets you resize images by pixels or percentage directly in your browser. All processing happens locally using HTML Canvas — your files are never uploaded to a server.
Choose exact pixel dimensions, pick a common preset like 1920×1080 or 1080×1080, or scale by percentage. The tool preserves the original file format and maintains quality during resizing.
How it works
1. Upload one or more images (up to 10 at a time, max 10 MB each).
2. Choose a resize mode — enter exact pixel dimensions or select a percentage.
3. Click "Resize now" and download your resized images individually or as a ZIP archive.
The resizing algorithm uses high-quality bicubic interpolation to keep your images sharp. Aspect ratio is preserved by default so your photos never look stretched. If you also need to reduce file size, try our Compress Image tool.
Frequently Asked Questions
Is this tool really free?
Yes, 100% free with no limits on usage. There are no watermarks, no sign-up required, and no hidden fees.
Are my images uploaded to a server?
No. All resizing happens directly in your browser using HTML Canvas. Your images never leave your device.
What image formats are supported?
The tool supports JPG/JPEG, PNG, and WebP. The output format is always the same as the input — no conversion happens.
Can I resize multiple images at once?
Yes, you can upload up to 10 images and resize them all with the same settings in one batch. Download them individually or as a single ZIP file.
Will resizing reduce image quality?
Downscaling (making images smaller) preserves quality well. The tool uses high-quality interpolation. Upscaling is disabled by default to avoid blurry results — uncheck "Do not enlarge" if you need it.
What is the maximum image size?
Each file can be up to 10 MB and up to 8000 pixels on the longest side. You can process up to 10 files per batch.
