Image Target Size

Pick a limit like “under 200 KB” and get the best-looking JPEG or WebP that fits. Quality is lowered first; pixels are reduced only if that is not enough. Nothing is uploaded.

Target size (at most)

1 KB is counted as 1,000 bytes, so the result also fits a site that counts 1,024.

How to use

  1. Choose the target size (100 KB / 200 KB / 500 KB / 1 MB / 2 MB, or enter a custom value).

  2. Drop images or click “Choose files” (multiple supported). Processing starts immediately.

  3. Check the resulting size, quality and dimensions in the list. Use “Compare” to inspect against the original.

  4. After changing the output format or the max image size, click “Redo with these settings”.

  5. Download images one by one or all at once as a ZIP.

What it does

Finds the best quality under the limit

A binary search over quality 45–92 finds the highest quality that fits. Every step measures the real JPEG / WebP output size, so the result is guaranteed to fit, not estimated.

Downsizes only when quality is not enough

If even quality 45 is too big, the long edge is reduced by about 15% per step and the search repeats. Losing pixels is the last resort.

Already small enough? Left as is

JPEG / WebP files already under the limit are output unchanged by default (switchable). You can also let a PNG stay PNG when it fits.

See what was achieved

For each file: final size, quality, dimensions before and after, and number of tries — plus a before/after slider.

Batch and ZIP

Process up to 200 images at once. Failures do not block the rest, and a report.csv can be added to the ZIP.

Use cases

  • Meet a “file must be under 200 KB” rule on application, job or government forms
  • Fit phone photos under an email or chat attachment limit
  • Adjust ID photos or identity documents to an upload limit
  • Bring many images to the same size limit in one go

Limits & notes

  • Up to 50 MB per file, 200 files per batch and 100 megapixels per image.
  • Targets count 1 KB as 1,000 bytes, so the result also fits a site that counts 1,024.
  • If the image still does not fit after shrinking to about 200 px on the long edge, it is shown as failed. Raise the target or crop first.
  • Text and line art degrade quickly at low quality. Check with “Compare”.
  • Transparent areas become the chosen background colour (white by default) when saving as JPEG.
  • Uses your device’s CPU and memory; large images can take a few seconds.

Privacy & safety

Reading, compressing and zipping all happen inside your browser. Images are never sent to or stored on a server. Only the compression engine (WebAssembly) is downloaded the first time you use it.

FAQ

How do I make an image under 200 KB?
Choose “200 KB” as the target and add your image. The tool finds the highest JPEG / WebP quality that fits in 200 KB and shrinks the dimensions only if lowering quality is not enough.
How much quality will I lose?
It depends on the gap between the original size and the target. The list shows the achieved quality (45–92) and whether the image was shrunk, and “Compare” shows it next to the original. The tighter the limit, the more quality and pixels are lost.
Is a KB 1,000 or 1,024 bytes?
This tool counts 1 KB as 1,000 bytes (200 KB means at most 200,000 bytes), so the result fits whichever way the site you upload to counts. Pick the limit as it is.
Can I keep a PNG?
PNG has no quality setting to tune, so it is output as PNG only when it already fits under the target (switchable). Otherwise it is converted to JPEG / WebP.
Is the location data (EXIF) removed too?
Images that are re-encoded lose their EXIF, including location. An image that already fit and is returned as it is (the “keep original” setting) keeps its EXIF. To be sure location data is gone, check it with the image metadata cleaner.
Are my images uploaded?
No. All processing happens in your browser; images never leave your device.
