Format is locked while images are being compressed

JPEG is already a lossy format, but cameras, phones and design tools save it at quality settings far higher than the web needs — often alongside several megabytes of embedded thumbnails and EXIF data. imgBoost re-encodes at a quality level tuned for screen viewing and discards the metadata, which typically halves the file without a difference you can see.

How JPEG compression works

JPEG discards detail your eye is least likely to notice, and the quality setting controls how aggressively. Photos straight from a camera are commonly saved at quality 95 or higher, well past the point of diminishing returns — dropping to the mid-80s often removes half the file size while remaining visually identical on a screen. Stripping EXIF data removes camera model, lens, timestamps and GPS coordinates, which shrinks the file further and avoids publishing location data you may not have intended to share.

Best uses for JPEG

  • Photographs and camera output
  • Hero images and banners
  • Product photography for online stores
  • Any complex image with smooth gradients

When JPEG is the wrong choice

JPEG has no transparency channel, so it cannot replace a PNG that needs a transparent background. It also handles sharp edges poorly — text, screenshots and line art develop visible halos around high-contrast boundaries. And because every save re-applies lossy compression, repeatedly editing and re-saving the same JPEG degrades it cumulatively. Compress from your original file rather than from an already-compressed copy.

JPEG compression FAQs

Will compressing my JPEG make it look worse?

Not noticeably. Most JPEGs are saved at a quality far above what a screen can show. imgBoost targets the range where file size drops sharply but visible quality does not, so the compressed image looks the same at normal viewing size.

What is the difference between JPG and JPEG?

Nothing — they are the same format. The three-letter .jpg extension is a leftover from older systems that only allowed three characters. imgBoost handles both identically.

Does compression remove EXIF data from my photos?

Yes. Camera model, lens settings, timestamps and any GPS coordinates are stripped. That reduces file size and prevents you from unintentionally publishing the location where a photo was taken.

Can I compress the same JPEG twice?

You can, but you should not. JPEG is lossy, so each pass discards a little more detail permanently. Always compress from your original file rather than from a previously compressed copy.

Should I convert my JPEGs to WebP instead?

For images going on a website, usually yes — WebP is typically 25 to 35 percent smaller than JPEG at matching quality and is supported by every current browser. Switch the output format toggle above to WebP to convert as you compress.
