Image Compressor — Batch, Target Size, No Upload
Shrink JPG, PNG and WebP images in batches of up to 50. Pick a quality, or give a maximum file size and let the tool find the best quality that fits. Resize, convert to WebP and compare before and after with a slider, then download each image or all of them as a ZIP. Your images are processed on your own device.

What Image Compressor does
Hit an exact size limit
Need every photo under 200 KB for a form or a listing? Set the limit and the tool searches for the highest quality that fits, image by image.
Whole folders at once
Drop in up to 50 images, change a setting once and every file is redone. Download them one by one or all together as a ZIP.
Resize for the biggest win
Most photos are far larger than any screen shows them. Capping the width at 1920 pixels usually saves more than any quality setting — and it is resampled in steps, so edges stay clean.
Convert to WebP
WebP is typically a quarter to a third smaller than JPEG at the same visual quality, and supported by every current browser.
Compare before you download
Drag a divider across the original and the compressed version to check faces, text and fine detail for yourself.
Your photos stay on your device
Images are decoded and re-encoded by your own browser. Nothing is uploaded, so there is no file limit per month and nothing to delete afterwards.

How it works
Add images
Drop them on the page or choose them — up to 50 at a time.
Choose quality or size
Set a quality, or a maximum file size per image.
Resize or convert (optional)
Cap the width or height, or switch the output to WebP.
Check and download
Compare before and after, then download each image or a ZIP of all of them.
How people use it
Upload limits
Get photos under the size an application form, job portal or email attachment will accept.
Faster websites
Smaller images are the quickest page-speed win. Resize and convert to WebP before uploading to your site.
Listings and marketplaces
Prepare a batch of product or property photos to the same size and quality in one go.
Freeing up space
Shrink a folder of phone photos you want to keep, without the quality loss you would see from messaging apps.
Frequently asked questions
Are my images uploaded?
No. Your browser decodes each image, redraws it and encodes it again, all on your device. There is no upload, no server copy and no monthly limit.
What quality should I use?
For photos, 70–80 is the usual sweet spot: files are much smaller and the difference is hard to see at normal size. Go lower for thumbnails, higher for images people will zoom into. Use the comparison slider to check faces and text, where artefacts show first.
How does "hit a file size" work?
It encodes the image, checks the size and halves the quality range each time — seven or eight tries — to find the highest quality that fits under your limit. If even the lowest quality is too big, it says so. Set a maximum width then, because fewer pixels is the only thing that shrinks it further.
Why is my PNG not getting much smaller?
PNG is lossless, so there is no quality setting to lower. The browser's PNG encoder is also basic, so a PNG that was already optimised can come out larger — in which case the original is kept. For photos saved as PNG, switch the output to WebP or JPEG; for screenshots with transparency, WebP keeps the transparency and is far smaller.
Does compressing remove the photo's location and camera data?
Yes, whenever the image is re-encoded, because only the pixels are redrawn. The exception is a file kept unchanged because compressing would have made it bigger — its metadata is untouched. To remove metadata without re-compressing, use the EXIF remover.
Which formats can I use?
JPEG, PNG and WebP in and out. AVIF and BMP files can be opened if your browser supports them and saved as one of the three. Some browsers, Safari among them, cannot save WebP from a web page; the tool tells you, and you can choose JPEG instead.
Is there a size or file limit?
Up to 50 images at a time and 50 MB per image. Very large images use a lot of memory while they are processed, so a phone may be slower than a computer.
