Image Compressor
Compress JPG, PNG and WebP images in bulk, right in your browser. Up to 20 files at once, with a before and after preview.
Your files never leave your device. Privacy
Phone photos are often 3 to 8 MB each, which is far more than most websites, forms and emails need. This compressor makes them much smaller while keeping them looking the same on screen, and it does all the work on your own device.
How to use the Image Compressor
-
Add your images
Drag and drop up to 20 JPG, PNG or WebP files into the box above, tap it to choose files, or paste a screenshot with Ctrl+V.
-
Pick a level
Recommended suits most photos. Choose Light when quality matters most, Strong for the smallest files, or switch to Target size and type a limit such as 200 KB.
-
Check and download
Drag the before and after slider to compare, then download each image or grab everything in one ZIP file.
Features
-
Private by design
Compression runs on your phone or computer. Your photos are never uploaded, stored or seen by anyone else.
-
Batch processing
Compress up to 20 images in one go and see the saving for every file and for the whole batch.
-
Before and after slider
Check faces, text and edges side by side before you download anything.
-
Target size mode
Need a file under 100 KB for an exam form or job portal? Set the limit and the tool finds the best quality that fits.
-
Format choice
Keep the original format or convert to JPG, PNG or WebP. WebP is usually smaller than JPG at similar quality.
-
Never worse than the original
If a file cannot be made smaller in its own format, you get your original back instead of a bigger copy.
When to use it
Online forms and job portals
Government sites, university applications and recruitment portals often reject photos above a fixed limit such as 50 KB, 100 KB or 2 MB. Target size mode is made for this.
Email attachments
Many mail services cap attachments at around 20 to 25 MB. A handful of phone photos can pass that, while compressed copies fit with room to spare.
Faster websites and blogs
Heavy images are one of the most common reasons a page scores poorly on PageSpeed. Smaller hero and product images help Largest Contentful Paint on mobile data.
Freeing up storage
Compressed copies of photos you rarely open at full size take a fraction of the space on a full phone or laptop.
JPG, PNG or WebP: which should you choose?
JPG is best for photos. It handles natural detail and smooth gradients well and is accepted everywhere, which makes it the safest choice for forms.
PNG is best for screenshots, logos and anything with sharp text or transparency. This tool shrinks PNG files by reducing the number of colors, which often cuts the size by more than half while keeping text crisp.
WebP works in all current browsers, supports transparency and is usually smaller than both. It is a great choice for websites, but some older apps and upload forms still do not accept it.
What quality setting should I use?
For photos viewed on a phone or laptop, a quality between 70 and 80 is very hard to tell apart from the original. That is what the Recommended preset uses.
Go lower only when you need the smallest file, and always check the slider. Skin tones, blue skies and small text are where compression shows first.
Frequently asked questions
Is this image compressor really free?
Yes. There is no sign up, no watermark and no daily limit. You can compress up to 20 images per batch and run as many batches as you like.
Are my images uploaded to a server?
No. Your images are processed by your own browser on your own device. Nothing is sent to The Zarq or any other server, and the tool keeps working even if you go offline after the page loads.
How much smaller will my images get?
Photos straight from a phone or camera usually shrink by 50 to 80 percent at the Recommended setting with no visible difference on screen. Images that were already compressed may shrink much less. The tool shows the exact saving for every file.
How do I compress an image to a specific size like 100 KB?
Switch to Target size mode, type the size you need in KB and the tool does the rest. It lowers the quality step by step and, only if needed, reduces the dimensions until each file fits under your target.
Does compressing a PNG keep transparency?
Yes, as long as you keep the output as PNG or choose WebP. If you convert a transparent PNG to JPG, transparent areas are filled with white because JPG does not support transparency.
Why did one of my files get bigger?
If an image was already heavily optimized, re-encoding it can produce a slightly larger file. When you keep the same format, the tool gives you the original back so you never download something worse.
Which browsers does it work in?
Current versions of Chrome, Edge, Firefox, Safari and Samsung Internet on desktop and mobile. Saving as WebP needs a browser that can create WebP files; if yours cannot, the option is hidden.
