Features – Image Compression

Pro — Single, Power User, Agency

Your images are slowing your site down. Fixing it takes one afternoon.

Most WordPress sites accumulate hundreds of unoptimised images over time. No one compresses them because doing it manually at scale is not practical. Mediapapa does it in bulk, once, then automatically on every new upload.

How Mediapapa handles compression

Bulk compress your existing library

Select files by filter or all at once. Mediapapa compresses in the background using Action Scheduler — your site keeps running. No quality loss. No monthly cap. Compress 50 files or 5,000.

Convert to WebP or AVIF

WebP saves 25–35% over JPEG at equivalent quality. AVIF saves more. One action compresses and converts. Mediapapa serves what the browser supports — no manual fallback management.

Auto-compress on upload

Enable once in settings. Every new upload lands in your library already compressed. Your library never accumulates unoptimised files again.

What WordPress does natively — and where it stops

WordPress resizes images on upload and generates multiple thumbnail sizes. That is intentional and useful. What it does not do: compress the original, convert formats, or give you any visibility into which files are oversized. A 4 MB JPEG stays 4 MB in your library unless you act on it. There is no native way to identify which files need attention, let alone fix them in bulk.

Compression plugins solve this, but most work on a per-image basis or impose monthly quotas. Mediapapa includes unlimited compression as part of the Pro plan — not as a separate subscription, not with a monthly counter to watch.

What the savings look like in practice

A 2 MB JPEG typically compresses to around 1.2–1.5 MB without visible quality change. Convert to WebP and it drops to roughly 800 KB. AVIF brings it closer to 600 KB. For a site with 500 images averaging 1.5 MB, compression frees 300–500 MB of storage and delivers meaningfully faster page loads — measurable in Google PageSpeed Insights and Core Web Vitals.

Common questions

No. Mediapapa uses lossless and smart lossy compression via the Mediapapa API. Visual quality stays the same. File size shrinks. If you want to verify before compressing your entire library, run a test batch on 10–20 files first.

No. Compression runs in the background using WordPress Action Scheduler. It processes files in batches without blocking your site’s front end or admin.

WebP is mature and supported by all modern browsers — Chrome, Firefox, Safari, Edge. It saves 25–35% over JPEG. AVIF is newer and saves more (30–50% over JPEG), but browser support is still growing. Both are available in Mediapapa. WebP is the safer choice for broad compatibility today.

No. All paid plans include unlimited compression via the Mediapapa API. There is no monthly counter, no overage charge, and no throttling. Compress your entire library in one go if you want.

Mediapapa replaces the file with the compressed version. If you want a safety net, take a full backup before running bulk compression — which you should be doing anyway before any bulk operation on your library.

The Free version identifies files that would benefit from compression — you can see which images are oversized or in an inefficient format. Compression itself (bulk convert and optimise) requires a paid plan from $49/year.
