Compress Image to 600 KB

Compress an image to 600 KB — for desktop wallpapers and large-format screen backgrounds.

Supports JPEG, PNG, WebP, GIF, BMP and more — up to 50 MB

How to compress an image to 600 KB.

The target is preset, so this takes three steps — plus what to expect at 600 KB.

1
Step 1

Upload your image

Click upload or drag and drop any JPEG, PNG, WebP, SVG, or GIF file from your device.

2
Step 2

Target is already set to 600 KB

This page is preset to 600 KB, so there is nothing to type. Choose JPEG or WebP output for the most efficient result at this size.

Step 3

Compare, then download

Press compress and check the result against your original in the slider. Roughly 3400 × 3400 px is the realistic pixel budget at 600 KB — download when it looks right.

Getting the best results

Match your actual screen resolution

A 2560 × 1440 monitor gains nothing from an 8K image. Matching the panel avoids both the softness of an undersized file and the waste of an oversized one.

Watch for banding in skies

Wallpapers are viewed for hours, so gradient banding that would pass unnoticed on a web page becomes irritating. If a sky bands at 600 KB, raise the target for that image.

Compressing an image to 600 KB.

What 600 KB is actually for, what it can hold, and how to get there without wasting quality.

What 600 KB is good for

600 KB is a wallpaper size. A desktop background is displayed at full screen resolution and stays on screen all day, so softness and banding are noticeable in a way they never are in a web thumbnail.

Unlike web imagery, there is no transfer cost to optimise here — the file is downloaded once and reused, which changes the priorities entirely.

Where this size is required

Desktop and laptop wallpapers, digital signage backgrounds, video conferencing backdrops, TV and display screensavers, and large-format screen art.

What to expect at 600 KB

Photographs remain clean to roughly 3400 × 3400 pixels, which covers a 4K display with pixels to spare.

Frequently asked questions.

Everything you need to know about compressing images to 600 KB.

Match your display: 1920 × 1080 for a standard monitor, 2560 × 1440 for QHD, 3840 × 2160 for 4K. Supplying more than the panel can show only wastes storage.

Barely. It is decoded once and held in memory by the desktop, so unlike web images there is no repeated transfer cost. Optimise for appearance rather than size.

Because you look at it for hours. Gradient steps that would pass unnoticed on a web page become genuinely irritating on a background.

For a photographic JPEG, roughly 3400 × 3400 px is the practical ceiling before compression becomes visible. Flat graphics, screenshots, and document scans do considerably better, because they contain less fine detail to preserve.

No. Images are processed on our secure server only to perform the compression and are deleted immediately after your download. They are never stored, shared, or accessed by anyone.
