How to Resize an Image in Your Browser
Drop in your image
Add a PNG, JPG, or WebP file up to 25MB. Its current width and height load automatically into the controls.
Set your target size
Type an exact width or height, or tap a 25–100% preset. With aspect-ratio lock on, the other dimension follows so nothing stretches.
Download the resized image
Your browser redraws the image at the new size with high-quality smoothing and saves it — the format is kept the same.
Everything You Need to Resize Images
Resizing sounds simple, but the details — aspect ratio, quality, and privacy — are where most tools fall short. Here's how this one handles them.
Exact pixel control
Enter the precise width and height you need in pixels. No vague small/medium/large presets — you get the exact dimensions a spec or upload form asks for.
Aspect-ratio lock
Keep the lock on and changing one dimension recalculates the other automatically, so your image never looks squashed or stretched.
High-quality resampling
Downscaling uses the browser's high-quality image smoothing, keeping edges clean and text legible instead of jagged.
No upload — 100% private
The resize happens entirely in your browser tab. Your images are never sent to a server, so there's nothing to leak or retain.
When You Need to Resize an Image
Fixed dimensions show up everywhere online. These are the moments a quick resize saves you.
Fit upload size requirements
Profile photos, ID uploads, and marketplace listings often demand exact pixel dimensions. Resize to spec and your upload goes through the first time.
Prepare images for the web
Serving a 6000px camera photo where a 1200px image will do wastes bandwidth. Resize down before uploading to make pages load faster.
Make thumbnails and avatars
Generate a clean square or fixed-size thumbnail for a video, product, or profile without opening a full image editor.
Standardize a batch
Bring photos to a consistent width for a gallery, catalog, or document so everything lines up neatly.
Resize Images Without Uploading Them
Most online resizers upload your image, resize it on their server, and hand back a download. Doing it locally is faster and keeps your images yours.

Pro Tips for Resizing Images
Downscale, don't upscale
Making an image smaller keeps it sharp. Enlarging past its original size can only invent pixels, so it always looks softer — start from the highest-resolution original you have.
Keep the aspect ratio locked
Unless you deliberately need a different shape, leave the lock on. Matching only one dimension to a target and letting the other follow prevents distortion.
Resize once from the original
Each save of a JPG re-compresses it. Resize from your original file rather than from an already-resized copy to avoid stacking quality loss.
