Image compressor

Compress an image below 500 KB

Choose the 500 KB compressor when the upload limit is larger and preserving detail matters. It creates a local JPEG result below the configured target.

Practical details from this tool's current settings.

Supported input

JPG, PNG, WebP files up to 25 MB.

Tradeoff

The output is always JPG in this compression workflow.

Simple process

How it works

  1. 1

    Select a JPG, PNG or WebP and check whether your existing file already suits the destination.

  2. 2

    Choose Compress image unless a JPEG already fits; in that case it is ready without re-encoding.

  3. 3

    Review the output size, dimensions and fine detail. A larger budget still does not guarantee unchanged quality.

  4. 4

    Choose Download JPEG or Download original JPEG, and keep the source for future edits.

Useful for

  • Portfolio photo previews where a 500,000-byte cap allows more room for texture than the smaller targets.
  • Photographs in presentations or shared documents where a byte cap matters more than original camera resolution.
  • Product photos with detailed surfaces when the destination permits a 500 KB JPEG; inspect any small labels separately.

Limitations

  • The output is always JPG in this compression workflow.
  • Transparent areas become white because JPEG does not support alpha transparency.
  • Quality is chosen automatically and dimensions can shrink if quality changes alone cannot meet 500,000 bytes. This is not a full-resolution archive export.

Questions

Frequently asked questions

Use it when your upload limit allows a larger file and you want to preserve more image detail than smaller targets can keep.

Usually it will be smaller for large files, but a converted PNG or WebP may be larger than the original while still staying below 500 KB.

No. The JPG download is created locally in your browser and is not stored as a public result page.

A JPEG at or below 500,000 bytes is reused without re-encoding. Choose Download original JPEG to save it unchanged. Use Compress JPG if you intentionally want further reduction; a target is a maximum, not an instruction to fill the entire budget.

PNG and WebP inputs are converted even when already small, so JPEG may be larger and transparent areas become white. Keep the original if it already suits your destination. Use Compress PNG or Compress WebP when retaining that format and transparency matters more than this JPEG cap.

Check Output dimensions and Technical details for resizing. Return to the original and use Compress Image for manual quality and dimensions when there is no strict 500 KB maximum. If the target search fails, no above-target file is offered; resizing or a permitted crop can reduce the source workload.
