Use this tool for a specific image job

Prepare a JPEG for a form or attachment that requires no more than 50,000 bytes.

Recommended settings

Target: 50 KB
Unit: KB = 1,000 bytes for a decimal form limit
Reduce dimensions: on when quality alone cannot reach the target
Confirm the exact byte count and visible detail before submission

Limits to check

The default KB unit is 1,000 bytes; KiB is 1,024 bytes. With automatic dimension reduction disabled, an image may remain over the target and will be clearly flagged. JPEG does not preserve transparency or animation.

Real before-and-after compression example

On 8 September 2026, we encoded our own brand graphic locally and verified each output against the decimal byte limit. Browser encoders may choose slightly different quality levels, so always check the result shown for your file.

Before: PNG, 1,729 × 910 pixels, 2,274,496 bytes.

Actual JPEG output below the 50KB decimal limit — After: JPEG, 1,729 × 910 pixels, 49,572 bytes — 97.8% fewer bytes.

Reproduce it with the preset above. Your result can differ by browser; acceptance depends on the exact byte count, not the rounded label.
