Resize Image
Change width and height in pixels.
Resize Image Online by Pixels
Resize Image changes the exact horizontal and vertical pixel resolution of your image using high-quality browser resampling, with optional aspect-ratio locking to prevent distortion.
Supported formats: JPG · PNG · WebP · SVG · Processing: 100% browser-local HTML5 Canvas & Blob APIs
How to use Resize Image
- Upload your JPG, PNG, WebP, or SVG image.
- Keep "Lock aspect ratio" checked to scale proportionally, or uncheck it to enter independent width and height values.
- Enter your target Width (px) and Height (px), and select your preferred output format and quality.
- Review the live preview and click Process to download the resized image.
Practical use cases
- Resizing social media headers, blog thumbnails, and e-commerce product photos to exact pixel specs.
- Downscaling 4000 × 3000 px camera photos to 1200 × 900 px for web publishing.
- Preparing fixed-dimension avatars or portal uploads that specify exact pixel widths and heights.
Common problems & solutions
Solution: Enable "Lock aspect ratio" before typing your new width or height, or use Aspect Ratio Crop first if your target ratio differs from the original photo.
Solution: Raster images contain a fixed grid of pixels; enlarging them interpolates between pixels. Start from the highest-resolution source available.
Are my images uploaded to AJN Buzz?
No for this tool. Processing runs in your browser and no sign-in is required.
What is the maximum pixel dimension supported?
AJN BUZZ IMAGE decodes high-resolution camera photos up to 50 megapixels and safely caps output canvases at 16.7 megapixels (up to 8,192 pixels per side) so exports never crash mobile Safari or desktop browser memory.
Does resizing in pixels strip EXIF metadata?
Yes. Because the resized image is freshly rendered on an HTML5 Canvas, hidden camera EXIF and GPS tags are not copied to the exported file.
