Free Image Compressor — Reduce Image File Size Online

October 8, 2026 · 1 min read · By the DollarWise team

Shrink oversized images before you upload them — faster websites, smaller email attachments, and less storage used. Upload a JPG, PNG, or WebP, choose a quality level, and compare the result with the interactive before/after slider. Everything runs in your browser; your files are never uploaded anywhere.

How it works




Drag the slider above to compare the original (right) with the compressed version (left).

Everyday uses

  • Blog and website owners — smaller images mean faster pages and better SEO; Google ranks fast sites higher.
  • Freelancers — email portfolios and invoices as attachments without hitting size limits.
  • Sellers — compress product photos before listing on marketplaces for quicker uploads.
  • Students — shrink screenshots for assignments and reports that must stay under a file-size cap.
  • Social media — compress before posting to control quality instead of letting apps do it badly.

Rule of thumb: quality 80% is the sweet spot for photos — visually identical to the original at a fraction of the size. Drop to 60–70% only when every kilobyte counts.
