Frequently Asked Questions
How do I compress a JPEG without losing quality?
Use 75–85% quality. JPEG compression discards detail the eye barely notices, so at these settings photos usually shrink 50–70% with no visible difference. Use the before/after slider to confirm on your own image.
What is the difference between JPG and JPEG?
None. They are the same format. The .jpg extension exists because older Windows versions limited extensions to three letters.
Why is my compressed JPEG bigger than the original?
Your original was already heavily compressed. Re-encoding it at a higher quality adds data. Lower the quality slider below the original's level, or reduce the dimensions with the Image Resizer.
Can I compress a JPEG to an exact size like 100KB?
Yes. Use Compress to 100KB or the Reduce Image Size tool, which searches for the best quality that fits any KB or MB target.
Is compressing JPEGs here private?
Yes. Compression runs in your browser using the Canvas API. Your photos are never uploaded, stored or seen by anyone.
