Resize Image Online
Resize images by pixels or percentage. Maintain aspect ratio. Free, private, browser-only.
How Image Resizing Works
img.awajis resizes images using high-quality bilinear interpolation directly in your browser. Set exact pixel dimensions or scale by percentage. The aspect ratio lock ensures your images aren't stretched or distorted. All processing uses WebAssembly for near-native speed.
Tips for Resizing
- For web: most images work well at 1200-1920px wide
- For social media: each platform has optimal sizes (e.g., 1080x1080 for Instagram)
- For email: keep images under 800px wide for best compatibility
After resizing, compress your images for even smaller files, or crop to remove unwanted areas.
Frequently asked questions
How do I resize without distortion?
Keep the “maintain aspect ratio” option on so width and height scale together. Setting both freely can stretch or squash the image.
Can I make an image larger?
Yes, but enlarging can’t add detail that isn’t there, so upscaled images look softer. Downscaling always keeps quality.
What size should I use for the web?
Match the display size — for example around 1080px wide for full-width images, or 800px for in-article photos — to keep pages fast.
Is it private?
Yes — resizing happens in your browser with no uploads.
Does resizing reduce file size?
Yes — fewer pixels means a smaller file. Downscaling a large photo to the size you actually display is one of the biggest space savings you can make.
What are common social media image sizes?
As a guide: Instagram square 1080×1080, Facebook cover 820×312, and Twitter/X header 1500×500. Crop first if the aspect ratio doesn’t match.
How do I resize to an exact file size?
Resize to smaller dimensions, then run the Compress tool and adjust quality until you hit your target — the two steps together control the final size.
Will resizing blur my image?
Downscaling stays sharp. Upscaling beyond the original resolution can look soft because the extra detail simply isn’t there to enlarge.
