Works with JPG, PNG, and WebP files. For best results on photos, try 60 to 80 percent quality. You will barely notice a visual difference, but the file size drops significantly.

How to Compress Your Image

1

Upload your image

Drag and drop your JPG, PNG, or WebP file into the box, or click to browse your device.

2

Adjust the quality

Move the slider to choose how much to compress. 60 to 80 percent is usually the sweet spot for photos.

3

Download your file

Click Compress, then download your smaller image. Nothing was ever uploaded, so it stayed private the whole time.

Getting a photo down to the size you need

Upload forms often cap files at 100 KB, 200 KB or 1 MB, and email services usually stop around 20 to 25 MB. This tool does not have a box where you type a target size. You move the quality slider, press Compress, and read the new size next to the original. If it is still too big, lower the quality a little and run it again. Most people get there in two or three tries.

The format you pick and the pixel size of the photo matter as much as the slider. A 4000 pixel wide photo from a phone stays heavy even at low quality. If you are still over the limit, make it smaller first with the resize tool and compress it after.

Output formatGood forWhat to expect
JPEGPhotos, forms, email attachmentsSmall files that open everywhere. No transparency.
WebPYour own website or blogOften a bit smaller than JPEG at the same look. Very old browsers cannot show it.
PNGScreenshots, logos, transparent imagesThe quality slider is switched off and the size barely changes.

For photos, 70 percent is a sensible place to start. Screenshots with small text turn fuzzy at low quality, so keep those higher or leave them as PNG.

Frequently Asked Questions

Is this image compressor really free?

Yes, completely free, with no limit on how many images you compress. There is no account required and no watermark added to your files.

Will compressing reduce the quality of my image?

A little, but usually not in a way you will notice. Compression works by removing data that is less visible to the human eye. Staying between 60 and 80 percent quality keeps images looking sharp while still cutting file size significantly. Going much lower starts to introduce visible blurriness or blocky patches.

Is my image uploaded to a server?

No. Everything happens directly in your browser using your device’s own processing power. Your image never leaves your computer or phone, which also means it is faster since there is no upload or download wait.

What image formats are supported?

You can upload JPG, PNG, or WebP files. You can also choose to convert the output format, for example uploading a PNG and downloading it as a compressed JPEG for extra savings.

Why did not my PNG file get much smaller?

PNG is a lossless format, meaning the quality slider has limited effect on it. If you need a real size reduction on a PNG, switch the output format to JPEG or WebP, and you will usually see a much bigger drop in file size.

Is there a file size limit?

There is no hard limit built into the tool, but since compression happens on your own device, very large files (10MB or more) may take a few seconds longer to process depending on your device’s speed.

Can I compress multiple images at once?

Right now, the tool handles one image at a time to keep things fast and simple.

How do I compress an image to 100KB or 200KB?

There is no field for a target size, so it takes a little trial and error. Upload the image, set the output to JPEG or WebP, and lower the quality until the compressed size shown is under your limit. If a large photo will not get there without looking rough, resize it to smaller dimensions first and then compress it.

Which is better for photos, JPEG or WebP?

WebP is usually a little smaller for the same look, which makes it a good pick for your own website. JPEG is the safer choice when the file is going into an email, a job application or an online form, because every program can open it.

Does compressing change the width and height of my image?

No. The pixel dimensions stay exactly the same and only the file size changes. If you want smaller dimensions as well, use the Resize Image tool.

Can I compress a photo for email without it looking blurry?

Usually, yes. A JPEG at 60 to 80 percent quality is hard to tell apart from the original on a normal screen. Before you send it, open the downloaded file and zoom in to be sure you are happy with it.
