Image requirement guide

Compress an image to 200 KB

Keep enough visual detail for screenshots and photos while staying below a 200 KB requirement.

Keep more detail while staying upload-ready

The 200 KB preset is a better starting point for screenshots and images where small text or edges need to remain legible. It still checks the actual encoded bytes, and it keeps the output name separate from the original.

Do not let a generous limit hide a wrong format

Some destinations require PNG for transparency or a particular color behavior. Choose the format explicitly when the destination says so, then review the warning about transparency and the measured output before the file leaves the browser.

Questions people ask

Can a PNG pass a 200 KB limit?

Sometimes. PNG compression does not use the same quality slider as JPEG or WebP, so the result may still fail if the canvas contains complex photographic detail.

Is the ZIP created on a server?

No. ZIP bytes are assembled locally in the browser after the individual outputs have been validated.

How to use this tool

Use the 200 KB preset when an upload allows a larger file and retaining detail matters more than achieving the smallest result. It starts with JPEG output, a 200 × 1024-byte maximum, and a higher initial quality than the tighter fixed-size presets. Actual bytes are checked after encoding. If quality tuning cannot pass and dimensions are not fixed, the browser may proportionally reduce the canvas before validating again.

What to choose and what you get

What to choose

  • one supported local image

Result

  • a separate processed image copy or local measurement report

Supported use

  • Photos and screenshots whose stated upload allowance is 200 KB and whose output can be encoded as JPEG.
  • Measured byte validation with more initial quality headroom than the 20, 50, and 100 KB preset settings.

Before you start

  • A file below the ceiling is valid even when it is not exactly 200 KB; no minimum is implied by this preset.
  • The route does not certify readability, color fidelity, metadata retention, or third-party acceptance.

Supported formats

  • Accepted formats: JPG, PNG, WebP, HEIC, AVIF, GIF, BMP.
  • Output formats: JPG, PNG, WebP.

Browser support and permissions

  • Modern browser with JavaScript, a supported image decoder, and enough memory for the selected image.
  • No camera, microphone, or screen permission is needed.

Choose the right settings

  • Pick 200 KB when that is the actual maximum and a less compressed image is preferable.
  • Do not use a tighter 20, 50, or 100 KB page unless the receiving destination requires the smaller ceiling.
  • Use /custom if 200 KB must be combined with exact dimensions, crop placement, transparency, or a non-default format.

Worked example

A detailed screenshot must fit below 200 KB without sacrificing as much clarity as a smaller preset would require.

Starting facts

  • The image contains small interface text.
  • The relevant rule is a 200 KB maximum with no exact dimensions.

Observed operation: Use the local JPEG search against 200 × 1024 bytes, preserving the source canvas unless further reduction is necessary.

Review the result: Zoom to inspect text and edges, then verify the receipt reports bytes below the entered ceiling.

Boundary: The larger ceiling improves available encoding headroom but does not guarantee lossless output or external acceptance.

What you can do

Retain more photographic or screenshot detail while enforcing a 200 KB JPEG upper limit.

If it does not work

  • A very detailed or fixed-dimension image can still exceed 200 KB after the available quality search.
  • Changing output to PNG removes the lossy quality control used by the preset's JPEG workflow.
  • Canvas safety limits, an invalid raster signature, or browser decode failure can stop export before byte validation.

Things to know

  • The measured result still needs review against the intended destination or use.

Privacy boundary

The selected image stays in the current browser session and is not sent to an Aftermath processing service. How local processing is verified.

What this tool verifies

Checks the displayed limits and reports or creates a separate processed image copy or local measurement report from one supported local image.

Check before sharing

A local measurement or export does not guarantee acceptance by an external destination.
