Compress Image

Compress images online for smaller files

Drop one image or a whole batch, pick output format and quality, then generate lighter files for websites, docs, email, and social posting.

This workflow keeps compression practical: track per-file progress, retry any failed image, remove items you do not need, and export everything in a single ZIP.

Image compression quick stats

Typical reduction range
About 30% to 80%, depending on source format and image detail
Best candidates
Large photos and mixed-content images headed for web or social
Biggest benefit
Faster page loads, easier uploads, and lower bandwidth usage
Main risk
Artifacts around edges, gradients, and small text at low quality

Compression settings that work in practice

For photos, WebP or AVIF usually gives the best size reduction, while JPEG quality around 80-85 is a strong compatibility baseline.

For screenshots, diagrams, and transparency-heavy assets, PNG often remains the cleaner option. Use the list preview and size change indicators to decide file by file.

How to choose quality and output format

  • Start in the middle: begin with moderate quality, then lower only if detail stays acceptable.
  • Match format to image type: photos often favor WebP or AVIF, while transparency-first assets may favor PNG. The format comparison guide covers when each option wins.
  • Review hard areas: inspect text, logos, and high-contrast edges where compression damage appears first.
  • Batch by destination: keep separate outputs for web hero images, social posts, and archive copies.

Tradeoffs and safe compression workflow

Image compression removes data to cut file size, so there is always a balance between visual fidelity and transfer speed. Lighter files improve UX and can support better performance metrics, but overly aggressive settings can make assets look soft or noisy.

When not to compress aggressively

  • Print-bound images: preserve source quality for layouts, proofs, and production handoff.
  • Brand-critical visuals: keep careful gradients, fine shadows, and logo edges intact.
  • Master archives: retain originals so future edits do not compound quality loss.

Compress image questions, answered

How much can image compression reduce file size?

Many images shrink by roughly 30% to 80%, but the real result depends on source format, pixel dimensions, and visual detail. Photos usually compress more than screenshots with tiny text.

Will compressed images look worse?

They can if quality is pushed too low. A moderate quality range keeps most web and social images visually clean, while aggressive settings may introduce blur, banding, or edge artifacts.

Should I choose WebP, AVIF, JPEG, or PNG?

Use WebP as a practical default for broad compatibility and strong savings. AVIF can deliver the smallest files but can be slower to encode. JPEG is still useful for legacy workflows, while PNG is better for transparency-heavy graphics and screenshots.

When should I avoid compressing an image?

Avoid heavy compression for master archives, print production, or assets with small text and precise gradients. Keep originals so you can export alternate sizes and quality levels later.
