What Is an Image Compressor?
An image compressor is a tool that makes image files smaller so they load, upload and send faster. It re-encodes the picture more efficiently and discards detail that is hard to see, so the same image takes up fewer kilobytes. A good image size reducer lets you choose how much quality to trade for a smaller file, instead of guessing.
How to Compress an Image Online
To compress an image online, add a JPG, PNG or WebP file to the Pixbee Image Compressor, pick a quality level or a target size, select Compress Image, then download the result. The whole process runs in your browser and usually takes a few seconds.
-
Add your image
Drop a JPG, PNG or WebP file into the compressor, choose one from your device, or paste it from your clipboard. Files up to 25 MB are supported.
-
Choose how much to compress
Use the quality slider, pick Smallest for maximum savings, or set a target size such as 100 KB, 200 KB, 500 KB or 1 MB. You can also save the result as JPG, PNG or WebP.
-
Compress the image
Select Compress Image. The file is processed right in your browser, so there is no upload to wait for.
-
Compare the results
Check the original and compressed sizes and the percentage saved, then drag the before-and-after slider to inspect the quality.
-
Download the compressed image
Save the new file. It keeps your original file name with "-compressed" added, and your original file is never changed.
How the Pixbee Image Compressor Works
The Pixbee Image Compressor runs entirely in your web browser. It decodes your image on your device and re-encodes it with your settings. Unless you choose a different format under Save as, a JPG stays a JPG, a PNG stays a PNG and a WebP stays a WebP.
JPG and WebP: quality re-encoding
JPG and WebP images are re-encoded at the quality you choose, from 10 to 100%. A lower quality removes more fine detail and produces a smaller file. Smallest uses a strong 30% setting for the biggest savings.
PNG: a smaller color palette
PNG is a lossless format, so lowering the quality works differently. Pixbee reduces the image to a palette of up to 256 colors, chosen to match the original as closely as possible, and saves an optimized indexed PNG. Transparent areas stay transparent. If a PNG already uses 256 colors or fewer, it is repacked without losing anything.
Target size: the highest quality that fits
When you set a target such as 100 KB, the compressor tries a series of quality levels and keeps the highest one that fits. It scales the image down only if it can't get small enough at full size, and it tells you when that happens. If recompressing would make the file bigger, you get your original file back instead.
Lossy vs Lossless Compression
Lossy compression makes files much smaller by permanently removing detail that is hard to see. Lossless compression keeps every pixel exactly as it was but saves less space. JPG and WebP below full quality are lossy. A standard PNG is lossless, although reducing its color palette, as this tool does, is a lossy step.
| Aspect | Lossy | Lossless |
|---|---|---|
| What changes | Fine detail and subtle color variation are discarded | Nothing; the image is identical |
| File size savings | Large | Small to moderate |
| Best for | Photos, website images, email attachments | Logos, screenshots, text and graphics you will edit again |
| In this tool | JPG and WebP below 100% quality; PNG palette reduction | PNG at 100% quality; PNGs that already fit in 256 colors |
Supported Formats and Limits
JPG / JPEG
The most common format for photos. JPG uses lossy compression, so lowering the quality setting can reduce the file size significantly while the image still looks natural. JPG has no transparency.
PNG
A lossless format that supports transparency, used for screenshots, logos and graphics. Pixbee compresses PNG files by reducing the color palette, which keeps edges sharp and transparent areas intact.
WebP
A modern web format that supports lossy compression and transparency. WebP files are usually smaller than JPG files of similar visual quality, which makes WebP a good choice for websites.
Limits
- Input formats: JPG/JPEG, PNG and WebP. By default the compressed file keeps the same format, or you can save it as JPG, PNG or WebP.
- Maximum file size: 25 MB. Maximum resolution: 64 megapixels.
- One image at a time.
- Animated PNG and animated WebP, GIF, HEIC, AVIF and SVG files are not supported.
- Some phones and tablets, including iPhone and iPad, limit how large an image the browser can process. Very large photos may need to be resized first.
- If your browser cannot create WebP files, a WebP result is saved as JPG, or as PNG when the image has transparency, and the tool tells you.
Compress an Image to a Specific Size
Many upload forms set a maximum file size. Choose Target size to compress an image to 50 KB, 100 KB, 200 KB, 500 KB or 1 MB, or enter your own limit in KB or MB. The compressor searches for the highest quality that fits the target. Very small targets may require reducing the image dimensions, and because every image compresses differently, the result is approximate. The tool always shows the final size and tells you if the target could not be reached.
Recommended Compression Settings
These are good starting points. Every image compresses differently, so check the before-and-after slider before you download.
| You want to | Mode | Try first |
|---|---|---|
| Speed up a website or blog | Quality, saved as WebP or JPG | 70–80% for photos |
| Meet an upload limit on a form | Target size | The form's limit, for example 100 KB or 200 KB |
| Email or message a photo | Quality or Target size | 75%, or a 500 KB target |
| Keep a logo or screenshot crisp | Quality, saved as PNG | 80–100% |
| Get the smallest practical file | Smallest | Check text and gradients afterwards |
What Happens to Your Image
Your image never leaves your device. The Pixbee Image Compressor reads, compresses and previews the file inside your browser, so Pixbee's servers never receive a copy. The image stays in your browser's memory until you compress another image or leave the page.
The compressed file does not include the original's EXIF metadata, such as camera details and GPS location. The photo's orientation is applied to the image itself, so it still displays the right way up.
To improve the tool, we record anonymous usage details such as the file type, the file size and the settings used. We never record the image itself or its file name. Read more in our privacy policy.
Why Compress Images?
-
Faster website loading
Images are often the largest files on a web page. Smaller images download sooner, especially on mobile connections, which helps the main content appear faster.
-
Upload limits
Reduce image file size to fit the limits on application forms, job portals, marketplaces and content management systems.
-
Less storage
Compressed images take up less space on your phone, computer and cloud storage.
-
Easier sharing
Smaller files send faster by email and messaging apps and are less likely to hit attachment limits.
Smaller images can improve how quickly a page shows its main content, which is part of a good page experience. Compression alone doesn't guarantee better search rankings, but oversized images are one of the most common reasons pages load slowly.
Frequently Asked Questions
How do I compress an image online?
Open the Pixbee Image Compressor, add a JPG, PNG or WebP image, choose a quality level or a target size, and select Compress Image. Compare the result with the original, then download the compressed file. Everything happens in your browser.
Does compressing an image reduce quality?
Compression removes data, so a smaller file always involves some trade-off. At moderate settings, around 70 to 85% quality, the difference is usually hard to see. Very low quality or a very small target size can cause blur, blocky areas or color banding, so use the before-and-after slider to check.
How can I reduce image size without losing quality?
Use a moderate quality of about 75 to 85% and compare before and after. For no loss at all, save a PNG at 100% quality: PNGs that already use 256 colors or fewer are repacked losslessly, and larger ones are re-saved as lossless PNG, although that usually saves little space.
Can I compress JPG images?
Yes. JPG and JPEG images are re-encoded at the quality you choose. Photos saved at a high quality often shrink considerably without a visible difference.
Can I compress PNG images and keep transparency?
Yes. Pixbee reduces a PNG to a palette of up to 256 colors and keeps transparent areas transparent. The result is still a PNG. For photos, JPG or WebP is usually much smaller than PNG.
Can I compress WebP images?
Yes. WebP images are re-encoded as WebP at your chosen quality. If your browser cannot create WebP files, the tool saves a JPG instead, or a PNG when the image has transparency, and tells you when that happens.
Can I compress an image to 100 KB?
Yes. Choose Target size and select 100 KB, or enter any size in KB or MB. The compressor looks for the highest quality that fits. It reduces the image dimensions only if the target cannot be reached otherwise, and it tells you if the target still cannot be met.
Can I convert an image to WebP or JPG while compressing?
Yes. Use the Save as option to download the compressed image as JPG, PNG or WebP. Converting a transparent image to JPG fills the transparent areas with white, because JPG does not support transparency.
Why does it say my image is already well optimized?
Some images are already compressed efficiently, and saving them again at your settings would make the file larger. When that happens, Pixbee gives you your original file rather than a bigger one.
Are my images uploaded or stored?
No. Compression runs in your browser, so your image never leaves your device and Pixbee never receives a copy. The image is cleared from the page when you compress another image or leave the page.
Does compressing a photo remove EXIF and location data?
Yes. The compressed file is re-encoded without the original EXIF metadata, such as camera details and GPS location. The photo's orientation is applied to the image itself, so it still displays the right way up.
What is the maximum file size?
You can compress images up to 25 MB and 64 megapixels. Some mobile browsers, including Safari on iPhone and iPad, cannot process very large photos, so resize those first if compression fails.
Can I compress multiple images at once?
Not at the moment. The compressor handles one image at a time. After downloading, select Compress Another Image to continue with the next file.
Is the Pixbee Image Compressor free?
Yes. The image compressor is free to use, with no sign-up and no watermark.
