JPEG is still the default camera export on most phones. “Compress jpg online” and “reduce jpg file size” searches come from people hitting email 25 MB caps or Shopify image limits. This page is the JPEG-specific compressor so the H1, examples, and FAQ match that query instead of a generic image page.

Why JPG compresses so well

JPEG throws away high-frequency chroma that eyes barely notice. That is why a 4.8 MB camera JPEG often becomes 1.2 MB at quality 80 with the same 4032×3024 pixel box. PNG cannot do that for photographs — it is a lossless filter plus deflate, so photos stay heavy.

Each re-save stacks artifacts. If you will edit further, keep a master PNG or original HEIC. Compress JPG is for the file you actually send.

JPG vs WebP for the same photo

If the destination supports WebP, converting then compressing often beats JPEG at the same visual quality. If the destination is Outlook, WhatsApp compression, or an old CMS, stay on JPEG. This tool always emits JPEG so the extension stays .jpg.

Frequently asked questions

Is compress jpeg the same as reducing dimensions?

No. This tool keeps width and height and only changes the JPEG quantization. Use Resize JPG if you also need fewer pixels.

Why did my JPEG get slightly larger?

A file that was already saved at quality 40 can grow if you re-encode at 90. Drop the slider until the output is smaller than the original.
