About resizing JPG images
This page resizes JPG photos in your browser. The usual reason is a size limit somewhere else: a profile picture that must be 400 by 400, a listing photo that may not exceed 1920 pixels, an email attachment that should not be ten megabytes, or a batch of holiday photos that are far larger than any screen. Type the width or height you need, or a percentage, drop in one photo or twenty, and download the results. Nothing is uploaded, and your photos never leave your device.
How to resize a JPG
Steps
- Under Resize by, choose Pixels and type the width or height you need. With Keep aspect ratio on, the other side is worked out for you. Or choose Fit within to shrink every photo that is larger than, say, 1920 by 1080 while leaving smaller ones untouched.
- Keep Output format on Same as input so a JPG stays a JPG. Choose JPEG explicitly if you want to adjust the quality slider; 85 is a good default for photos.
- Drag your JPG files onto the drop area, paste them, or choose files. Each photo is resized as soon as it is added and shows its old and new size.
- Download each photo, or Download all as ZIP when you resized more than one.
Privacy
Everything runs in your browser. Your photos are never uploaded to our servers, and the resized files are created on your device. The EXIF block that phones and cameras write into every JPG, including GPS position, time and camera model, is removed from the result, and photos stored sideways with a rotation flag are turned upright first.
Quality and file size
Why resizing makes the file smaller
A JPG's size grows roughly with its pixel count. Halving the width and height leaves a quarter of the pixels, so the file shrinks to roughly a quarter as well, before any change to the quality setting. For an upload limit, resize first and only then lower the quality if you still need to.
Re-encoding
JPEG is a lossy format, so saving a resized photo re-encodes it once. At quality 85 the difference is invisible on a normal screen. Avoid resizing the same photo repeatedly; go back to the original each time instead.
Enlarging a JPG
Making a photo larger does not add detail; pixels are interpolated and the result is softer. It is fine for a modest increase, for example to meet a minimum size, but a small photo will not become a sharp poster.
Common sizes
- Profile pictures: 400 × 400 or 800 × 800. Set width and height to the same value with aspect ratio on; the photo fits inside the square.
- Full-width web photos: fit within 1920 × 1080 or 2560 × 1440.
- Email attachments: fit within 1280 × 1280 keeps most photos under half a megabyte.
- Thumbnails: 300 pixels wide with the height following.

The Image Resizer accepts PNG, WebP, AVIF, BMP and GIF as well, and this page works for all of them. Screenshots and graphics are better served by Resize PNG. To convert a JPG to another format without resizing, use the Image Converter; to put photos into a PDF, use Images to PDF.
