Compress Image to 30 KB

Compress an image to 30 KB — comfortable for ID photographs and small enough for a dense product grid.

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

How to compress an image to 30 KB.

The target is preset, so this takes three steps — plus what to expect at 30 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 30 KB

This page is preset to 30 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 780 × 780 px is the realistic pixel budget at 30 KB — download when it looks right.

Getting the best results

Set a consistent budget across a catalogue

When every thumbnail on a page targets the same size, the grid loads evenly instead of one heavy image stalling the rest. Use the Bulk Compressor to apply 30 KB across a whole folder in one pass.

Sharpen slightly after resizing

Scaling a photo down softens it a little before compression even starts. A light sharpen at the new dimensions makes a 30 KB thumbnail look noticeably crisper than an unsharpened one at the same size.

Compressing an image to 30 KB.

What 30 KB is actually for, what it can hold, and how to get there without wasting quality.

What 30 KB is good for

30 KB is the point where an identity photograph stops being a compromise. Portals that specify a 20–50 KB range are happiest around here, and the result no longer shows the tell-tale softening that a tighter target produces around eyes and hair.

It is also a sensible budget for e-commerce thumbnails. A category page showing forty products at 30 KB each carries 1.2 MB of imagery, which is manageable on mobile in a way that 100 KB thumbnails are not.

Where this size is required

Government and recruitment photo uploads in the 20–50 KB band, e-commerce category thumbnails, team or staff directory photographs, and blog post thumbnail images.

What to expect at 30 KB

Portraits at ID dimensions are clean and detailed. General photographs hold up to roughly 780 × 780 pixels, which comfortably covers thumbnail and small-card use on a website.

Frequently asked questions.

Everything you need to know about compressing images to 30 KB.

It is a strong default. At typical thumbnail dimensions of 300–400 pixels, 30 KB gives a sharp image while keeping a grid of dozens of products light enough to load quickly on mobile connections.

Only very small. At 30 KB you have roughly a 0.6 megapixel image, which is fine up to about a passport-photo print and visibly soft beyond that. Print work needs a target measured in megabytes.

Twenty of them is 600 KB, which is a reasonable ceiling for a full page of imagery. Beyond that, lazy loading matters more than the individual file size.

Yes, for that copy. The compression is lossy and cannot be reversed, which is why you should always compress a copy and retain the original file.

At thumbnail dimensions, yes. If it is displayed larger than about 400 pixels wide on a high-density screen, it will look soft — export at double the display size instead.

For a photographic JPEG, roughly 780 × 780 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.
