Question 1

Does compressing reduce image quality?

Accepted Answer

PixelResize uses adaptive compression that removes data your eyes can't perceive. At the default setting most people can't tell the difference, and you can raise the quality slider any time.

Question 2

What is the maximum file size I can upload?

Accepted Answer

You can process images up to about 50MB. Because everything runs locally in your browser rather than on a server, there's no strict upload cap — very large or high-megapixel files simply take a little longer to handle on slower devices.

Question 3

Are my images uploaded anywhere?

Accepted Answer

No. All compression happens inside your browser tab. Your files never leave your device and are discarded the moment you close the page.

Question 4

Which formats can I compress?

Accepted Answer

JPG/JPEG, PNG and WebP are all supported. You can also convert between these formats using our dedicated converter tools.

Question 5

Does compressing images improve SEO?

Accepted Answer

Indirectly, yes. Smaller images load faster, which improves Core Web Vitals — especially Largest Contentful Paint (LCP), a confirmed Google ranking signal. In 2026's experience-led, mobile-first ranking systems, fast-loading pages also reduce bounce and are favoured in search and AI Overviews.

Question 6

What is the best image format for the smallest file size in 2026?

Accepted Answer

For photographs, WebP gives the best size-to-quality ratio and is supported by every modern browser. JPG remains the safest universal choice, and PNG is best for graphics with sharp edges or transparency. You can compress all three here.

Question 7

Can I compress several images at once?

Accepted Answer

Yes. Load multiple images and compress them one after another without re-uploading. Because processing is local, batch compressing dozens of files never hits a server quota or rate limit.

Question 8

How do I compress an image to an exact size like 100KB?

Accepted Answer

Set a target file size and the tool iteratively adjusts quality until the output lands at or just under your limit. We also have dedicated pages for common targets such as 20KB, 50KB, 100KB and 200KB.

Question 9

Does compression remove EXIF and GPS metadata?

Accepted Answer

Re-encoding drops most embedded metadata, including GPS coordinates and camera details. That makes files smaller and protects your privacy before you share them online.

Question 10

Does the compressor work on phones and tablets?

Accepted Answer

Yes. It runs in any modern mobile browser on Android and iOS with no app install, and processing happens on-device so it keeps working even on slow connections once the page has loaded.
