Compress Image to 90kb

Press Compress and your image lands at 90 KB, no typing needed. The compression runs in your browser, and nothing is uploaded. Up to 10 photos work in one batch. Each file gets its own download card in the popup.

90 KB: The Safe Side of a 100 KB Limit

Some portals reject files that sit right at their limit. A "100 KB max" field can bounce a 99.8 KB upload. Aiming at 90 KB removes that risk completely. You give up almost no visible quality for that safety. This page exists for people burned by borderline rejections.

Compress an Image to 90 KB

1. Add Images: Press Select Images or drag up to 10 photos in.
2. Press Compress: The 90 KB target is preset.
3. Download: Save files one by one, or all together as a ZIP.

When to Use 90 KB and When Not To

Use 90 KB when your form says 100 KB and rejections sting. Use the exact 100KB page when the portal is known to be relaxed. For a completely custom number, the reduce image size in KB tool takes anything you type. Photo fields asking for 80 KB have their own preset page too.

A Practical Trick for Batch Uploads

Uploading many files to one portal multiplies the rejection risk. One borderline file can fail the whole submission. Compressing the entire batch to 90 KB removes the gamble. Ten files at 90 KB upload faster than ten at 100 KB too. On slow connections that difference is easy to feel. The ZIP download keeps the batch together for record keeping.

Compressed on Your Device

No upload happens at any point. Your browser does the compression itself, even on mobile data. Nothing is stored on any server, ever. Your photos stay exactly where they started: with you.

Why Your File Says Exactly 88 KB

The tool compresses to the best quality that fits, then pads the file. Padding is empty data after the image ends. Viewers ignore it, so the picture is untouched. The point is the size on disk: portals see a consistent number. That is how the result reads 88 KB every time, not 71 or 84. Forms with a minimum size requirement accept it because of this.

FAQ

Why 90 KB instead of 99 KB?
Portals measure size in slightly different ways. A 10 KB margin clears every measuring method. A 1 KB margin does not always.

Does this work for PNG screenshots?
Yes. Screenshots compress very well and usually land far under 90 KB. The tool then pads them to the exact size, which portals accept.

Will the quality drop be visible?
Between 90 and 100 KB, almost never. The difference is fine grain, not detail.
