Up to 10 images at once

Free Image Compressor
This is the general version of our compressor. Instead of a fixed size, you choose how much to shrink, then download lighter copies of your JPG, PNG or WebP images. It runs in your browser, needs no account, and takes up to 10 images per batch.
Use it when you don’t have an exact KB limit and just want smaller files. For example, you might be speeding up a blog, freeing phone space before sharing an album, or getting photos under a messaging app’s cap. If a form names a size, the fixed-size tools are quicker: 50KB, 100KB, 200KB, 500KB and 1MB.
How to compress images
- Add up to 10 images with “Select Images” or drag and drop.
- Choose the compression level or target, and the output format (keep the original, or convert to JPG or WebP).
- Press Compress, then download each file or all of them.
Keep your originals and compressed copies safe
After you compress an image, it helps to keep both the full-size original and the smaller copy in one place, so you can grab the right file later for a form, an email or your website. pCloud is secure cloud storage that works on your phone and computer, and its Lifetime plan is a one-time payment if you’d rather not pay monthly.

Lossy vs lossless, in plain words
Lossy compression (what JPG and most WebP use) throws away fine detail the eye barely notices, and files get much smaller. Lossless compression keeps every pixel but saves less. For photos, lossy at a sensible level is almost always fine. For logos, screenshots with text, or graphics with sharp edges, PNG or lossless WebP keeps edges crisp.
Tips
- Websites: WebP is usually 25-35% smaller than JPG at similar quality, and all modern browsers support it. Our image formats guide goes deeper.
- Resize before you compress. A blog column is rarely wider than 1200 pixels. Shrinking a 4000-pixel image to that width saves more than any quality slider.
- Keep originals. Compressed copies are for sharing and uploading. Keep the full-size files backed up.
- Batch work: for hundreds of images or a whole WordPress media library, a plugin or service built for bulk work saves time. See our image compressor comparison.
What it doesn’t do
It doesn’t edit, crop, remove backgrounds, or compress video or PDF files. Animated GIFs may lose their animation if converted to another format.
Which output format should you choose?
- JPG: best for photos and for forms that list JPG/JPEG. It’s accepted almost everywhere.
- PNG: for screenshots, logos and graphics with text, or anything that needs a transparent background. It’s larger for photos.
- WebP: the smallest for websites and supported by all current browsers. Some government and older upload forms don’t accept it yet, so check first.
- Original Format: keeps whatever you uploaded. It’s the safest choice when you’re unsure.
A quick rule: if a person will view it on a web page, use WebP or JPG. If a form will receive it, use whatever the form lists.
FAQ
How much smaller will my images get?
Typical phone photos shrink by 60-90%. Images that were already compressed shrink less.
Is there a file size limit for uploads?
Very large files can be slow in a browser. If one fails, try it on its own or resize it first.
Are my images private?
They’re processed to create the compressed copies and are not published. Avoid uploading sensitive documents to any online tool if you can.
Does it add a watermark?
No.
