Free Online JPEG Compressor — Auto or Exact Size

Some workflows accept JPEG only and reject PNG or WebP. Upload a .jpg or .jpeg file, compress in your browser with auto mode on by default, preview the result, and download when the file looks right.

Auto compress balances quality and bytes for everyday JPEG uploads. Uncheck Auto in the compress panel when a form or PDF attachment names an exact kilobyte cap such as 100KB.

Comparison

Which Upload Limit Fits Your Form?

One hundred kilobytes in JPEG matches many HR caps — tighter than 200KB listings, looser than 50KB KYC.

Benefits

Why JPEG Is Required on These Forms

Passes MIME checks

Validators that block PNG still accept image/jpeg.

Efficient for portraits

Lossy JPEG fits skin tones into a 100KB budget.

PDF attachment friendly

Many PDF forms embed JPEG, not PNG, for photo fields.

Supported formats

JPEG vs JPG vs Other Formats at 100KB

PNG

Works well for
  • Ink signatures on white paper
  • Stamps and line drawings
  • Logos needing transparency

Heads-up: Uploading PNG to a JPEG-only field fails before size is even checked.

WebP

Works well for
  • Modern web upload widgets
  • Android-heavy portals
  • Re-saving an already compressed shot

Why try it: WebP is rarely allowed when the label says JPEG only — stick to .jpg here.

If the form accepts PNG, our 100KB all-format tool may be easier — this page is for JPEG-only rules.

Quality

What Changes at JPEG

Faces and ID text should stay readable at normal zoom — wide group shots need tighter crops.

Works well

  • Shoulder portrait
  • Plain wall

Reviewer-ready at normal zoom.

Usually OK

  • Light grain
  • Patterned tie

Still passes most portals.

Hard fit

  • Group photo
  • Night shot

Crop to one person or retake.

When to use

When to Use This JPEG Compressor

Use this page when the upload field says JPEG or JPG — auto compress handles most cases; uncheck Auto for an exact KB cap.

  • JPEG-only dropdown — Portal lists image/jpeg only
  • PDF photo attachment — Form asks for a JPG photo
  • HR ATS JPEG field — Employer site accepts JPEG only
  • PNG rejected — Validator blocks non-JPEG MIME types
  • All formats allowed — Use the all-format image compressor instead
Tips

Practical Notes for JPEG Compression

800 px long edge

Common profile-photo target before compression.

Even front lighting

Underexposed faces look muddy when compressed.

Shoulders-up framing

Matches most ATS and admission samples.

JPG not HEIC

Export JPEG properly from your phone.

Plain background

Busy patterns cost bytes you need for the face.

Re-check after upload

Some portals show a second size readout after save.

Format pick

JPG, PNG, or WebP at JPEG?

When the form says JPEG, save as .jpg — other formats fail even at the right kilobytes.

FAQ

Common Questions About Compressing JPEG Online

How do I compress JPEG to 100KB online?

Use the uploader at the top of this page: add your JPEG, confirm the 100KB cap, check the preview, and download locally.

Can I compress JPEG to 100KB online for free?

Yes. Upload a .jpg or .jpeg file, keep the 100KB target, preview the output, and download — no signup and no server upload.

Is it free to compress JPEG photos to 100KB?

Yes — upload, compress toward 100KB, and download. No payment required on this page.

Can I compress JPEG to 100KB without losing quality?

Some detail loss is normal at 100KB. Resize to the portal's width and height first — that keeps faces sharper than crushing quality on a huge original.

This tool outputs a JPEG image — not a PDF. Compress the photo first, then attach the JPEG where the PDF form asks for a picture under 100KB.

Is JPEG compression to 100KB processed on your servers?

No — processing runs in your browser when supported. The file stays on your phone or computer.

Can I compress JPEG to 100KB on Android or iPhone?
