    Our online image compressor tool handles large files quickly, so you get compressed results without slowing down your day.

Image compression done right

Ever hit 'your file is too big' when you're short on time, or run out of storage? We built this photo compressor to shrink file size and speed up sharing. Pick from three compression levels, each showing an estimated final size, so you can resize an image to 2MB or shrink it much smaller. And the options keep growing: our experts constantly update the toolset, rolling out new features and formats to give you more control!

Where our image compressor helps most

Most email providers block messages over 20 to 25 MB, and a few full-size photos can pass that on their own. Compress each one to around 3 MB, and several will fit comfortably in a single email.

Frequently asked questions

  • Why is it helpful to compress photo size?

    Compressing photo size reduces file storage needs and speeds up upload or download times. That makes it especially useful if you're a photographer, student, or content creator who works with images all day. Smaller files upload faster, share without hitting size limits, and keep your storage from filling up too quickly.

    Worried about quality? Find out how to reduce image file size while keeping the original look in the answer below.

  • How to compress images without losing quality?

    To compress images without noticeable quality loss, use online compressors like PDF Guru. A few things help you keep them sharp:

    • Start with a high-quality file. The better your original image, the better it looks after you reduce the file size.

    • Choose the right compression level. PDF Guru offers three levels, each with an estimated final size, so you can trade a little sharpness for a smaller file only when you actually need to.

    • Don't over-compress. Running an image through compression repeatedly degrades quality, so strike a balance between size and clarity rather than pushing for the smallest file every time.

  • Which image formats can I compress?

    You can compress common image formats like PNG and JPEG. Our tool handles both today, and we're planning to support more formats soon.

    Whether it's a photo from your phone or a graphic from your computer, just upload your image, and we'll handle the rest.

  • Are my images safe during compression?

    Whether your images are safe during compression depends entirely on where you compress them. With PDF Guru, they're protected at every step.

    We use industry-standard security to keep your files safe throughout the upload, compression, and download processes, and everything is stored on trusted servers. On top of that, PDF Guru is verified by Google Safe Browsing, which checks websites for malware, phishing, and other online threats.

  • Can I convert my images to a different file format?

    Yes, you can easily convert images to different file formats like JPG, PNG, PDF, Word, Excel, and PPTX. Just pick the format you want from the options, name your file, and save it.

    We built our image file size reducer around what people and businesses actually need today. Notice something missing? Let us know, and we'll look into it.

  • What platforms can I use your image size compressor on?

    You can use our image size compressor on any platform with a web browser, including Windows, macOS, Linux, Android, and iOS. Just open this page in your browser, upload your file, and we'll handle the rest. 

  • Why didn't my image get any smaller after compression?

    Your image didn't shrink much because it was likely already compressed, leaving little to reduce. A low compression level can have the same effect. Try a higher one and check the estimated final size before you download. Note that compressing the same image repeatedly won't help, as it reduces quality rather than file size.

  • How do I cancel?

    You can cancel anytime from your account settings or by contacting our support team. Your access stays active until the end of the current billing period.
