What is it?

A 100KB compressor is designed to hit the 'sweet spot' of online form uploads. 100 kilobytes allows the algorithm to retain enough data for a high-quality portrait while staying safely under legacy server limits.

Why it matters

When attaching a photo to a PDF resume, an oversized 5MB photograph can cause the entire PDF to bloat, causing it to bounce back from recruiter email firewalls. 100KB guarantees delivery.

Use Cases & Limitations

When to use

This target size is ideal for:

  • Embedding a professional headshot directly into a Word or PDF resume.
  • Uploading avatars to forums, Discord, or professional networks.
  • Sending multiple photos in a single email attachment.

When NOT to use

Do not use this strict limit if your portal allows up to 2MB or 5MB. If the server allows larger files, always use standard <Link to="/jpg-compressor">JPG compression</Link> to preserve maximum detail.

Technical Limitations

While 100KB is generous for a headshot, attempting to compress a massive panoramic landscape to 100KB will still result in significant loss of background detail.

Frequently Asked Questions

Is 100KB enough for a printed photo?

It is enough to print a small wallet-sized photo cleanly, but it will appear pixelated if you attempt to print it as a standard 8x10 photograph.

Does this work on iPhones?

Yes, you can upload a massive HEIC file directly from your iPhone camera roll, and our engine will convert and shrink it to a 100KB JPG automatically.
