Compress images
Compress images to make them smaller so they upload faster and fit size limits. Add your files, pick a quality, then tap Compress. It all runs in your browser, so your files never leave your device.
100% private. Your files are processed entirely in your browser and never uploaded.
Why compress images with frisqoo
Nothing is uploaded
Your images are read and compressed inside your browser. They never reach a server, so there is nothing to delete later.
Six formats, really smaller
JPG, PNG, WebP, GIF, SVG, and TIFF are each genuinely recompressed, not just relabelled.
Keeps what matters
PNG transparency stays clear and GIF animation keeps playing, frame for frame.
You set the balance
A quality slider lets you trade a little sharpness for a smaller file, and cap the longest side if you want.
A whole batch at once
Compress many images in one go, then download them one by one or together as a zip.
Free, with no caps
No sign-up, no watermark, and no daily quota. Your device memory is the only real limit.
How to compress an image
- Add your images. Drop them on the box or pick them from your device, one or many.
- Set the quality. A lower setting makes a smaller file; a higher one keeps more detail. You can also cap the longest side in pixels.
- Press Compress. Check the saving on each image, then download one at a time or all in a zip.
Your files never leave the page. Each image is read and compressed by your own browser, so nothing is uploaded and nothing is stored on a server.
Pick a quality, or cap the size
The quality slider is the main control. Slide it down for a smaller file, or keep it near 80 for a good balance on most photos. To shrink big camera images further, set a limit on the longest side in pixels. That is often the fastest way to cut the size of a large photo. If you drop in a BMP, tick Save BMP as PNG to save it in a far lighter format.
How much smaller will my image get?
It depends on the file. A large photo often drops by half or more. A small or already-tuned file may not change much, and comes back marked already optimized so you are not left guessing. You can see the exact saving next to each image before you download it.
Compress an image to a set size, like 1 MB
There is no box to type a target size into. Instead, lower the quality a little, press Compress, and check the new size shown next to the image. If it is still too big, drop the quality again or cap the longest side, and compress once more until it fits. It usually takes only a couple of tries.
Compress images for email or a website
For email, most services stop at around 20 to 25 MB, so lower the quality until each file is small enough, or send the whole batch as one zip. For a website, smaller images make pages load faster: use the lowest quality that still looks good, and cap the longest side to the width it is actually shown at.
Which formats can I compress?
These formats are genuinely made smaller:
- JPG, for photos.
- PNG, keeping any transparent background.
- WebP, for modern photos and graphics.
- GIF, keeping the animation, timing, and transparency.
- SVG, by trimming the file down.
- TIFF, packed smaller without losing a pixel.
- BMP, saved as a lightweight PNG when you tick Save BMP as PNG.
Does it keep PNG transparency and GIF animation?
Yes to both. A compressed PNG keeps its see-through areas, so logos and cut-outs stay clean. A compressed GIF keeps every frame and its timing, so the animation still plays exactly as before.
Is it safe to compress images here?
Yes. Many free image compressors upload your photos to their own servers to do the work. This tool does not. Your images are read and compressed right inside your browser, so they are never uploaded, stored, or seen by anyone else. That makes it a safe choice for personal photos, ID scans, and anything else you would not want sitting on a stranger's server.
Common ways people use Compress images
- Shrinking phone photos so they fit an email or upload limit.
- Making product or blog images lighter so a web page loads faster.
- Cutting a batch of images down before sharing them as one zip.
- Reducing a large scan or TIFF without changing its format.
- Keeping a logo's transparent background while making the PNG smaller.
FAQs about Compress images
How do I compress an image?
Add your images to the box, pick a quality level, then press Compress. Each image is compressed on your device, and you can save them one by one or all together as a zip.
Is it free? Is there a limit?
Yes, it is free, with no sign-up and no watermark. Add as many images as you like. The only real limit is your device memory, since all the work happens on your device.
Are my images uploaded anywhere?
No. They are read and compressed by your own browser. Nothing is sent to a server, so even private photos stay with you.
Will compressing lower the quality?
It can drop some fine detail to save space. Near the 80 setting most people notice no difference on a normal screen. Go lower only when you need a very small file.
Can I get a file down to a set size, like 1 MB?
There is no set-a-size box. Lower the quality, press Compress, and check the new size next to each image. Repeat until it is small enough.
Which formats can I compress?
JPG, PNG, WebP, GIF, SVG and TIFF are all made smaller. You can also add a BMP and tick Save BMP as PNG to compress it as a lightweight PNG.
Does it keep a PNG transparent background?
Yes. PNG compression keeps the see-through areas, so a logo or cut-out stays clean.
Does it keep a GIF animated?
Yes. GIF compression keeps every frame, the timing, and any transparency, so the animation still plays.
Can I compress a BMP?
Yes. Tick Save BMP as PNG and your BMP is saved as a PNG, a much lighter format, so it takes up far less space while looking the same.
Can I compress many images at once?
Yes. Add as many as you like, compress them together, then download them one by one or as a single zip.
Does it work on my phone?
Yes. It runs in any modern browser on a phone, tablet, or computer, with nothing to install.
