  2. Enter the target width and height in pixels, or click a preset like HD 1920×1080 or Square 1080×1080.
  3. Keep maintain aspect ratio checked to resize proportionally without distortion.
  4. Choose an output format — WebP for smaller files, PNG for transparency, or JPEG for sharing.
  5. If exporting to JPEG, pick a background fill color to replace any transparent pixels.
  6. Review the preview and the original size, new size, and dimensions, then click Download Resized Image.

Privacy and Client-Side Security

Privacy Guarantee: All resizing and format conversion occurs locally inside your browser. Your files and data are never transmitted, stored, or recorded on remote servers.

Many online image resizers ask you to upload your photos to their servers before they can process them. That creates real privacy risk, especially for personal or work images. TinyToolzz takes a different approach: the entire resize happens in your browser with the HTML5 Canvas API.

Your image is read into browser memory, resized on your device, and then prepared for download without a single network request carrying image data. Once you leave the page or click Reset, the image data is released from memory. Nothing is stored, logged, or shared.

Frequently Asked Questions

How do I resize an image without losing quality?
Load your image, enter the target width and height, and keep the aspect ratio lock enabled. The tool re-samples the image with high-quality smoothing directly in your browser. For photos, the WebP output at quality 80 preserves the most detail at the smallest file size.
Does locking the aspect ratio prevent distortion?
Yes. When the aspect ratio is locked, changing the width automatically updates the height in proportion to the original image, and vice versa. This guarantees the resized image keeps the same shape and never looks stretched or squashed.
Are my images uploaded to a server?
No. The Image Resizer runs completely in your browser using the HTML5 Canvas API. Your image is read from your device into browser memory, resized locally, and is never transmitted, stored, or recorded on any remote server.
What output formats are supported?
You can keep the original format or export as WebP, PNG, or JPEG. WebP offers the best compression for photos, PNG is lossless and preserves transparency, and JPEG is the most widely compatible format for sharing.
Can I make a small image larger with this tool?
Yes, the tool allows upscaling, but a small source image contains a limited amount of detail. Enlarging it spreads the same pixels across a bigger canvas, so the result can look soft or slightly blurry. For crisp results, resize from the largest original you have.
Is there a file size limit for resizing images?
Files up to 50 MB are supported, and each side of the output is capped at 10,000 pixels to protect your browser from running out of memory. There is no limit on how many images you can resize, and the tool is free with no sign-up.
