200 KB: compare detail using the same original
Do not force a file down to 50 or 100 KB just because a smaller preset exists. If your destination permits 200 KB, the extra budget can let the encoder retain a higher setting. Compare files generated independently from the original. Recompressing an already reduced JPEG adds another lossy step and does not undo the earlier loss.
For the textured sample in the table, both 100 and 200 KB preserve the 1200×900 dimensions. That makes their output files useful for comparing encoding artifacts without confusing a resolution change with a quality-setting change. Download the two outputs and examine a small region at the same zoom. This synthetic texture is a stress sample, not a prediction of your portrait or scan.
Measured 200 KB examples
Measured with the actual ExactKB compressor in Chrome 155.0.8059.84 on macOS, using decimal units, automatic dimensions and no size preset. Encoder percentages are settings, not measured detail retention. Results vary with the image and browser. Files are synthetic, contain no customer images, and are available below so you can reproduce the comparison.
The textured PNG input is 3,031,966 bytes at 1200×900. Download the textured original.
On a narrow screen, scroll the results table sideways to see all columns.
| Input / target | Output bytes | Output pixels | Encoder setting | Inspect file |
|---|---|---|---|---|
| Texture / 200 decimal KB / JPG | 185,764 | 1200×900 | 82% | Download output |
| Texture / 100 decimal KB / JPG | 95,925 | 1200×900 | 67% | Download output |
To reproduce: upload the matching original above, choose the target shown in the row (this page starts at 200 KB), turn off the 1024-byte option, leave Longest side on Automatic and select the table’s output format. Press Compress and compare exact bytes and dimensions. The decimal ceiling is 200,000 bytes; leaving binary units enabled instead permits 204,800 bytes.
When an attachment is still rejected
A 200 KB image budget is not a guarantee that a message or form accepts the attachment. Confirm the permitted format and any total limit for multiple files. Some services count the complete message or upload, rather than each image alone. If there is a separate pixel requirement, compare it with the result card; raising the byte target does not crop or validate the photograph.
Before using the download
If the result says “Could not fit”, its download is an above-limit best effort, not a successful compression. Do not upload it as a file that meets your cap. Try a larger permitted budget or prepare a simpler crop from the original.
Open the downloaded result and inspect the detail your task requires. Confirm format, actual bytes and both dimensions against the destination’s current instructions. A successful size badge does not validate composition or a separate minimum file size.
