Good to know
Most photos are much bigger than they need to be. A picture from a modern phone is often 3 to 6 MB, while a website, an email or an online form only needs a fraction of that. Compressing re-saves the image with smarter settings, so the file gets smaller while it still looks the same on screen.
The default setting keeps quality high and is right for most images. When a form has a strict limit, pick a target size instead. Quikdo lowers the quality step by step and only reduces the pixel size if quality alone can't get under the limit, so you keep as much detail as possible.
PNG files are compressed by reducing the number of colours, which works well for screenshots, logos and graphics. For photos saved as PNG, converting to JPG usually gives a much smaller file. Re-saved images don't keep hidden metadata such as camera details or GPS location.
Frequently asked questions
How do I reduce a photo from MB to KB?
Drop the photo in and pick a target like 100 KB or 50 KB. Quality is lowered first; if that isn't enough, the photo is made smaller in pixels until it fits.
Can I compress an image without losing quality?
At the default setting the difference isn't visible on screen. Very small targets like 20 KB do lower the quality, so check the before and after view.
Which formats can I compress?
JPG, PNG and WebP are saved in the same format. AVIF, GIF and BMP files are read too and saved as JPG or PNG.
Does it remove location data from my photos?
Yes. When an image is re-saved, details such as the camera and GPS location aren't copied across.
Is this image compressor free?
Yes. You can compress one image at a time, up to 10 MB, for free.
Are my photos sent anywhere?
No. They're compressed by your browser, on your device, and never sent to Quikdo.
