Compress JPEG to 240KB
A 240 KB JPEG target suits compact photos, listings and document previews with more room for recognizable detail than very small upload limits.

Balance photo clarity, resolution and predictable JPEG delivery.
Forty Kilobytes Above 200 KB
A 240 KB target gives the encoder 40960 more bytes than 200 KB in ResizeBox, which can preserve more texture or resolution without moving all the way to a 250 KB budget.
Good for Readable Document Previews
At 240 KB, cropped scans and document photos have more room for small text and edge contrast than very small JPEG targets, provided the output dimensions are not unnecessarily large.
Use the Extra 40 KB Before Losing Pixels
The encoder searches JPEG quality first. Compared with a 200 KB target, the additional 40 KB may be enough to keep the requested dimensions and avoid an automatic scale-down step.
Dimensions Can Assist
Width and height may be reduced if JPEG encoding alone cannot reach 240 KB.
JPEG-Only Result
Common image inputs are accepted, but every download is JPEG and transparency is flattened.
Local Private Conversion
The source stays in the browser during resizing and JPEG encoding.

240 KB JPEG Compression FAQ
Answers about photo clarity, conversion and final size.
ResizeBox treats 240 KB as 245760 bytes. It gives you 40960 more bytes than 200 KB while still using 10240 fewer bytes than a 250 KB target.
Often at suitable dimensions, depending on texture and noise.
Fine text, foliage, hair, fabric and camera noise are expensive for JPEG. A clean crop and moderate dimensions leave more of the 240 KB budget for the details users actually need to see.
Sometimes. The extra 40 KB gives JPEG more room before it needs to reduce width and height, but highly detailed images can still trigger automatic scaling.
Yes, but this page always exports JPEG.
Transparent pixels are flattened because JPEG has no alpha channel.
Target search is skipped, but JPEG export may still re-encode it.
No. Processing happens locally on your device.
Yes, our image resizing tool is completely free to use. No registration required, no watermarks, and no hidden fees. Simply upload your image and resize it to your desired dimensions.
