# Compress an Image to 300 KB

300 KB is a common limit for document uploads, listing photos and blog images. It is enough for a sharp Full HD photo, so the page keeps as many pixels as it can and only lowers the JPG quality until the file fits.

**Quick answer:** To compress an image to 300 KB, add it, keep the 300 KB target and press Compress to 300 KB. Photos are capped at 1920 pixels on the longest side and saved at the highest quality that fits; a typical phone photo lands at Full HD with no visible loss. Batch several images at once; nothing is uploaded.

## How to use it

1. Choose one or more photos or scans (JPG, PNG or WebP).
2. Keep 300 KB, or pick 200, 400 or 500 KB to match your limit.
3. Keep the same format, or choose JPG if the portal only accepts JPG.
4. Press Compress to 300 KB and download the images, as a ZIP if there are several.

## Enough for Full HD

At 300 KB a JPG of 1920 × 1440 pixels usually looks the same as the original on any screen. That is why this page keeps up to Full HD and adjusts the quality first:

| Image | At 300 KB |
| --- | --- |
| Phone photo (12 MP) | Full HD, sharp |
| Scanned A4 page | Text crisp at about 150 dpi |
| Screenshot | Usually already smaller as PNG |
| Very detailed photo (foliage, gravel) | Slightly lower resolution |

## Scans and documents

For a scanned certificate or ID that must be an image, 300 KB keeps small print readable. Save it as JPG unless the portal asks for PNG. If the portal wants a PDF instead, use [JPG to PDF](https://sharelargefilesfree.com/tools/jpg-to-pdf) and, if needed, [compress the PDF to 300 KB](https://sharelargefilesfree.com/tools/compress-pdf-to-300kb).

## For websites and listings

Marketplaces and blogs load faster with images around 200 to 300 KB. For a whole folder of website images, [Optimize images for web](https://sharelargefilesfree.com/tools/optimize-images-for-web) converts to WebP, which is smaller still at the same quality. Everything here happens in your browser.
