JPG Compressor

A typical iPhone JPG is 3–5 MB. Our compressor squeezes it to 500 KB–1 MB with no perceptible quality loss. That's the difference between a website that loads instantly and one that takes 5 seconds. Drop your JPG (or up to 50 of them), pick a quality level, download the smaller files. Free for 30 a day, no signup.

Why compressing JPGs matters

Image weight is the single biggest cause of slow web pages. A homepage with five uncompressed iPhone photos is 25 MB; the same homepage with properly-compressed versions is 2 MB — a 12× reduction in load time. Google measures page speed as a ranking signal, so heavy images literally cost search positions. Customers measure speed too, with the back button.

JPGs are particularly compressible because the format was designed for further compression — every JPG you save is already lossy, and re-encoding at lower quality just throws away more of the imperceptible detail. Going from quality 100 to quality 85 typically halves the file size with zero visible change. Going from 85 to 70 halves it again with only the most attentive viewers spotting the difference on flat-colour areas.

How to compress JPGs online

1. Drop the JPG(s). Single file, multiple files, or a folder. Free: 30/day; Premium: 300/day.
2. Pick a quality. Default is 85 — the web standard. 95 for archival, 70 for fast-loading thumbnails, 60 for tiny preview images. The slider previews the size delta before you commit.
3. Choose what to do with metadata. Default keeps EXIF (date, GPS, camera). Tick "strip metadata" to drop those — saves another 50–500 bytes per file and removes any privacy-sensitive GPS data.
4. Download. Output filename mirrors the input. Batch outputs are a single zip.

Quality settings explained

Quality 95 — virtually identical to the source. Use for archival or when print-quality matters. Typical compression: 30–50%.

Quality 85 — the web standard. Visually identical for normal viewing on monitors and phones. Typical compression: 60–80%.

Quality 70 — slight softening visible on flat-colour areas like sky if you look hard. Fine for content where the image is supporting, not the main attraction. Typical compression: 75–85%.

Quality 60 and below — visible blockiness on detailed areas, especially on dark or saturated colours. Use for thumbnails or placeholders only. Typical compression: 85–95%.

When to use other tools instead

For PNG files (logos, screenshots, transparent images), use our PNG Compressor — it's lossless and won't degrade quality. For modern browsers, our WebP Compressor typically produces 25–35% smaller files than equivalent JPG at the same visual quality. For mixed batches where you don't want to think about format per file, our Batch Image Optimizer picks the best codec per file automatically.

If your goal is making images small enough to email, you also might want to resize them first — a 4K photo dropped to 1080p is already 4× smaller before any compression.
