How to compress an image in 3 steps
Add your images. Drop them on the page, click Choose files, or paste an image with Ctrl+V. You can add many at once.
Let the compressor work. Each image is compressed as soon as you add it, at the Recommended quality. To aim for a given weight, switch to Target size instead. You see each size before and after, the percentage saved, and the total for all your images.
Download the result. Click Download next to an image, or Download all (ZIP) to get every image in one file, each with its original name and the extension of its format. You can cancel an image while it is being compressed, or remove it from the list.
Compress to a target size: 100 KB, 500 KB or 1 MB
Some forms and websites only accept images under a given weight. Choose Target size, then enter the size you need in KB or MB: 100 KB by default.
The compressor first looks for the quality that reaches your target. If that is not enough, it also reduces the image's dimensions. The result is at or under the target whenever possible.
If a target is too small for an image, the compressor tells you, and shows the smallest size it could reach. You can then choose a larger target, or crop or resize the image first.
Smaller files at the quality you choose
Compressing an image always means a trade-off between file size and quality: the lighter the file, the more details can be lost. The Recommended quality aims for files that are much lighter while still looking right on a screen.
To check the result, open the before and after comparison and move the slider over the image. If you need a sharper image, raise the quality in Settings; for a lighter file, lower it.
The compressor never makes a file heavier: if the compressed version would be bigger than the original, it keeps the original and shows Already optimized.
Resize and change the format
Large photos from a phone or a camera are often much bigger than a screen needs. In Settings, set a Maximum width or a Maximum height in pixels to make them smaller: the image keeps its proportions. Keep Original size to leave the dimensions as they are.
By default, each image keeps its format, except HEIC photos, which come out as JPEG, AVIF images as WebP and still GIFs as PNG. You can also save your images as WebP, JPEG or PNG. WebP often gives the lightest files for photos, JPEG opens everywhere, and PNG suits graphics, screenshots and images with transparency.
The compressor reads JPG, PNG, WebP, HEIC and HEIF, still GIF images, and AVIF when your browser can open it. Animated GIFs are not supported. To change the format without compressing, use the file converter.
Private by design: your images never leave your device
Your images are compressed inside your browser, on your device. They are never uploaded to Drime or to anyone else, which matters for personal photos, ID scans and work documents. Like the rest of the site, the page counts visits, but never your images.
The compressor also removes the hidden information photos carry, such as the GPS location, the camera details and other metadata, and keeps the photo the right way up.
Frequently asked questions
Does compressing an image reduce quality?
It can, a little. Compression makes a file lighter by removing details the eye barely sees, so the more you compress, the more you may notice. The Recommended quality keeps images looking right on a screen, and the before and after slider lets you check the result before you download it.
How do I reduce image size without losing quality?
Every compression is a balance between size and quality. To keep the most detail, raise the quality in Settings and compare the result with the slider. Setting a maximum width or height also saves a lot of space on large photos without visible loss when they are viewed on a screen.
How do I compress an image to 100 KB?
Choose Target size and keep 100 KB, the default, then add your image. The compressor looks for the quality that reaches 100 KB and, if needed, reduces the dimensions. If 100 KB can't be reached, it shows the smallest size it could get, so you can choose a larger target.
How do I make an image smaller in MB?
Drop it on this page: it is compressed at once and you see its new size. To aim for a given weight, choose Target size and enter it in MB or KB. You can also lower the quality, set a maximum width or height, or save it as WebP, which often gives the lightest photos.
Is it safe to compress images online?
With this compressor, yes: your images are compressed in your browser and never uploaded. They don't leave your device, and the hidden metadata such as the GPS location is removed from the compressed files. The page counts visits, but never your images.
What is the best image compression format?
For photos, WebP often gives the lightest files at a similar quality, and JPEG opens everywhere. PNG is better for graphics, screenshots and images with transparency. By default the compressor keeps each image in its format (HEIC photos come out as JPEG), and you can switch to WebP, JPEG or PNG in Settings.
How do I reduce image size for email?
Drop your photos on this page and choose Target size if your email service limits attachments, or set a maximum width in Settings: a photo for an email rarely needs its full size. Download them one by one, or all at once in a ZIP, and attach them to your message.
How do I compress a photo on iPhone?
Open this page in Safari, tap Choose files and pick your photos. The compressor reads iPhone photos in HEIC as well as JPG and PNG. HEIC photos come out as JPEG by default, a format that opens everywhere, or as WebP if you choose it in Settings. Then download the result.
