Resize, compress, and convert images. Supports JPG, PNG, WebP. All processing happens in your browser — nothing is uploaded.
Upload an image, set the target width and height, keep “Lock aspect ratio” checked to avoid distortion, choose the output format and quality, then click “Resize & Download”. The file is processed locally in your browser — no uploads, no privacy concerns.
Common targets: 1200px wide for blog headers, 800px for e-commerce listings, 1080×1080 for social posts. Lower the quality slider (70–85%) for web images to cut file size dramatically while keeping visuals sharp. For logos and graphics, prefer PNG; for photos, use JPEG.
Batch resizing is on the roadmap; for now, process one image at a time for best quality. If the result looks soft, increase quality to 95% or resize down in two steps instead of one large jump. The browser handles most formats, including HEIC on recent devices.
Set width and let the height auto-adjust when you only need one dimension, like a 1200px blog cover. For avatars, crop to a square first, then resize to 400px - resizing a non-square image distorts it. Always download and eyeball the result before publishing.
Images that are too large slow down your website, hurt SEO rankings, and frustrate visitors. Resizing images to the right dimensions makes them load faster, saves storage space, and ensures they display correctly on different devices. All processing happens entirely in your browser — nothing is uploaded to any server.
No. All processing happens in your browser using the Canvas API. Your image never leaves your device.
Input: JPG, PNG, WebP, GIF, BMP. Output: JPG, PNG, WebP.
Use the quality slider to control compression. JPEG at 80-92% offers good balance. PNG is lossless but larger. WebP offers best compression.
Performance depends on your device. Very large images (8000+ px) may take a moment to process.
