Resize images without stretching using crop, fit or locked ratio
Prepare an existing image for a banner, document, or social post without sending it to a server. Select a PNG, JPEG, or WebP, enter the output dimensions, and keep its aspect ratio for a proportional resize. For a different shape, choose a center crop or fit the whole image inside a colored canvas. Download a new file while keeping your original untouched. To resize an image without stretching, keep its aspect ratio locked; unlock it only when you intend to crop the picture or add a background to a different shape.
Ways to use the image resizer
Make a smaller image for a page or email.

Fit a landscape photo into a square canvas without stretching.
How to resize an image without stretching its proportions
Resizing changes pixel dimensions. A target frame with different proportions also requires a decision about what happens to the picture's edges.
Keep aspect ratio locked for proportional image resizing
Open a static PNG, JPEG, or WebP and leave the ratio locked when you want the whole picture at a smaller size. For a 2400 × 1600 source, a 1200-pixel width produces an 800-pixel height. Enlarging an image adds pixels but cannot recover missing original detail.
Choose the fit when the shape must change
Unlock the ratio for a different target shape. Crop fills the frame and can remove edge content; fit keeps the picture with padding; stretch changes its proportions. Inspect faces, circles, and lettering because they make unwanted stretching particularly easy to spot.
Check the processed copy
The tool accepts static PNG, JPEG, and WebP files, with browser memory and output-size limits. Select a format suitable for the result and inspect the new dimensions before downloading. Your original is not overwritten. If a large source fails, try a smaller output or another browser rather than repeatedly requesting the same allocation.

Image Resizer: questions & answers
Everything you need before your next download.
Can I resize an image without uploading it to a server?
Yes. The selected image is decoded and resized on your device. The file is not sent to a server, and the download is a separate copy.
How do I resize without distorting the picture?
Leave Keep aspect ratio enabled. If you need a different shape, unlock it and use Crop to fill or Fit with background instead of Stretch.
Does making a small image larger improve its detail?
No. Resizing adds pixels but cannot recover detail absent from the original. Prefer reducing an image or starting from a higher-resolution source.
Start your next creation with a simple image
Set the mood for a social post, refresh your wallpaper, or give a presentation a clean opening. Pick a canvas and make it yours.
Set the scene for your next post
Start with a 1080 × 1080 post or a 1080 × 1920 story. Pick colors that feel like you, download your background, then add photos and text in your usual editor.
Put your favorite colors on your screen
A soft sunset gradient or a quiet wash of color can make a screen feel like yours. Choose a 4K desktop canvas or a portrait phone size, then build a wallpaper around your own palette.
Give your next presentation a clean opening
Leave room for your ideas with a white canvas, or set the tone with a simple gradient. Start at 1920 × 1080, then add your title in a slide app or use the background for a project cover.
