Resize before squeezing quality
A 6000-pixel photo is often much larger than a form or web page needs. Reducing the longest edge to 1600 or 2000 pixels can save more space than pushing JPEG quality very low. Keep the full-size original for printing.

A practical example
Reduce photo weight before sharing
Large job photos or website images can be slow to send over a mobile connection. Compare the output size and appearance rather than choosing a quality value blindly.
- Add JPG, PNG or WebP images and choose the output format, quality and maximum edge.
- Convert, compare sizes and inspect fine details before downloading individual images or the ZIP.
A smaller file is not guaranteed for every input. PNG quality settings do not behave like JPG compression; try dimensions or another suitable format.

Reduce photo file sizes. Choose quality and dimensions, compare the result and download.
How to use the image compressor
- Add your images. Choose JPG, PNG or WebP images from your device.
- Balance size and detail. Choose JPG or WebP output, adjust quality and optionally reduce the longest edge.
- Compare and download. See the original and new file sizes. Inspect the preview and save each result.
Make the next step easier
Reduce what you send, keep what matters.
Good compression starts with the destination. A thumbnail, a customer photo and a large print do not need the same number of pixels or the same file size.
Use JPG for broad compatibility
JPEG works with most email clients, upload forms and older software. It suits photographs, but it cannot keep transparent areas. This tool fills transparency with white when JPG is selected.
Try WebP for your website
WebP is supported by modern browsers and can produce smaller photographic images while retaining transparency. Check that the website or publishing system accepts WebP before replacing an existing image.
Compare the result
Look closely at text, faces and sharp edges. A smaller number is not useful if the image no longer explains the work. Download a result only when its appearance and file size are suitable for the job.
Image compressor questions
Is this free without signing up?
Yes. There is no account, email gate, watermark or paid download. The limits shown in the tool keep processing manageable on your device. You can start another batch when you finish.
Are my files uploaded or saved?
No. File conversion happens in this browser tab. Your selected files and their contents are not sent to a Sysevo conversion server or saved to your account. Download the result before closing the tab. Normal website analytics may still record page visits.
Can I compress an image to exactly 100 KB or 200 KB?
There is no exact target-size guarantee. Lower quality or reduce the longest edge, then check the actual output size. Detailed photos need more data than simple images at the same dimensions. Run another conversion if you need a smaller file.
Does it compress PNG without changing the format?
This tool exports JPG or WebP, not optimised PNG. PNG input is decoded and converted. WebP can preserve transparency, while JPG uses a white background. Keep the original if you need lossless PNG output.
Why is the new file sometimes larger?
An image may already be well compressed, or the chosen format and quality may need more bytes. The tool reports larger outputs honestly. Try a smaller longest edge, a lower quality or the other format rather than assuming every conversion saves space.
What are the limits?
Add up to 25 still images, 20 MB per file and 50 MB in a batch. Each decoded image must be no larger than 24 megapixels. GIF, SVG, HEIC and video are not supported. Animated WebP files become one still frame.
