Compress JPG Online — Free, No Signup
Compress JPG online in seconds. Drop a photo, tune one slider, and download a smaller JPEG with the same look. No signup, no watermark, and we delete your file within an hour.
Why compress a JPG?
Smaller JPGs load web pages faster, slip past email attachment limits, and use less of your viewer's mobile data. A 4 MB phone photo typically drops to 600-900 KB at quality 70 with no visible loss for most viewers.
How the JPG compressor works
Our compressor re-encodes the image with the standard JPEG baseline encoder at the quality you pick on the slider. Quality 70 is the safe default. Quality 50 produces the smallest files that still look fine on screen. Quality 85 is for product photography where every edge counts.
Tips for the best result
Resize before compressing if the source is much bigger than the display size — a 5000 px photo destined for a 1200 px column compresses better after a resize. EXIF data is dropped on re-encode, which is a small privacy bonus.
Frequently asked questions
Does the JPG keep its EXIF data?
No. Re-encoding to JPEG strips EXIF metadata including GPS coordinates and device identifiers.
What quality level should I pick?
70 is the universal safe default. Drop to 50 for very small files. Raise to 85 if you need extra sharpness.
Will the file lose visible quality?
At quality 70 most viewers cannot tell the difference from the source. Heavy compression at quality 30 will show JPEG artifacts.
Is it actually free?
Yes. No signup, no daily cap on normal personal use, no watermark on the output. Display ads keep the site free.
Does it work on a phone?
Yes. The upload box opens the camera roll on mobile browsers directly.
