Image resizer: resize photos online
TL;DR: drop up to 50 photos, set the new size in pixels or percent or pick a preset, and download the results one by one or as a ZIP. Proportions are kept, crop to an exact size in one click, and EXIF location data is removed by default.

A photo straight from a phone is 4000 pixels wide and weighs several megabytes. Websites, social networks and online forms want something much smaller and often a fixed size. This resizer changes the size of a whole batch of photos at once, keeps the proportions and lets you crop to an exact frame such as 1080×1080 or 1200×630.
How to use it
- Add photos. Drag up to 50 files onto the box, choose them with the button or paste a copied image with Ctrl+V.
- Set the new size. Enter the width or the height in pixels and the other side follows the proportions, switch to percent, or pick a preset.
- Choose how to fit. When both sides are set, “Fit inside” keeps the whole picture, “Crop to fill” cuts the edges to fill the exact size, and “Stretch” changes the proportions.
- Check the format and EXIF. By default each file keeps its format and loses EXIF and GPS location. Switch to WebP for the lightest files.
- Download. Save the photos one by one or all together as a ZIP. Each row shows the old and new size in pixels and kilobytes.
Preset sizes
| Preset | Size, px | Aspect ratio | Where it is used |
|---|---|---|---|
| Instagram post | 1080×1080 | 1:1 | Square feed posts |
| Instagram portrait | 1080×1350 | 4:5 | Vertical feed posts |
| Stories / Reels | 1080×1920 | 9:16 | Stories, Reels, TikTok, Shorts covers |
| Open Graph | 1200×630 | 1.91:1 | Link previews in Facebook, LinkedIn, X, Telegram, Slack |
| App Store screenshot | 1290×2796 | about 9:19.5 | One of the accepted sizes for the 6.9-inch iPhone screenshot set |
| Full HD | 1920×1080 | 16:9 | Hero images, slides, video covers |
| Avatar | 400×400 | 1:1 | Profile pictures, team photos on a website |
Presets crop the photo around its centre so that it fills the frame exactly. If the subject is near the edge, crop the photo in an editor first or use “Fit inside” in the pixel mode: the whole picture stays and one side is simply shorter.
Resizing without losing quality
Making a photo smaller is safe: the resizer reduces it in several steps with high-quality smoothing, so fine lines and text stay clean and there are no jagged edges or moiré. Making a photo larger cannot add detail that is not there: an upscaled image looks softer. If you need a large picture, start from the original file rather than from a copy that was already reduced.
For a website, size the image for the largest place it is shown and double it for high-density screens: a picture shown at 600 px wide needs about 1200 px. Then compress it or convert it to WebP to make it lighter.
At YuSMP Group we build websites and keep them fast, and images and PDFs are the most common reason pages load slowly. If you need to fix the images of a whole site rather than a few files, see our web development service or start with the page speed test.
FAQ
How do I resize a photo without distorting it?
Enter only the width or only the height: the other side is calculated from the proportions. If you set both, keep “Fit inside” or “Crop to fill”. Only “Stretch” changes the proportions.
How do I make a photo exactly 1080×1080 or 1200×630?
Pick the preset or enter both sizes and choose “Crop to fill”. The photo is scaled to cover the frame and the edges are cut off evenly around the centre.
Can I resize many photos at once?
Yes, up to 50 photos per batch, each up to 100 MB. The same settings apply to every file, and you can download all of them as a ZIP.
Does resizing reduce quality?
Reducing the size keeps the picture sharp because it is smoothed in several steps. JPG and WebP are compressed again at the quality you choose; 85–92 looks the same as the original to most people.
What happens to EXIF and GPS location?
By default they are removed: the photo is redrawn and camera data, date and location are not copied. If you need EXIF, clear the checkbox; it is kept when a JPG is saved as JPG.
Are my photos uploaded to a server?
No. Photos are read and resized in your browser in a background Web Worker. Nothing is sent over the network.
Can I make a photo larger?
Yes, enter a bigger size or a percentage above 100. The browser fills in the new pixels by smoothing, so the result is softer than a real high-resolution photo.
Does it work on a phone?
Yes, in current Safari on iPhone and iPad and in Chrome on Android. Very large images are limited to about 16.7 megapixels by mobile Safari and are reduced to fit.
