Shrink photo file sizes without losing the details that matter
Large photos slow down everything — a WhatsApp catalog that takes forever to load, a website that fails Google's PageSpeed test, an email attachment that bounces because it's too big. Most phone cameras save photos at 3–5MB each by default, far larger than any screen actually needs to display them. This free image compressor re-encodes your JPG, PNG, or WebP photos right in your browser, typically cutting file size by 70–90% with no visible quality loss at normal viewing sizes.
Upload up to 20 photos at once and they're processed one at a time, so a full batch never overwhelms your browser tab — even on a mid-range phone. Adjust the quality slider to trade off file size against sharpness (75% is a solid default for web and WhatsApp use), and optionally cap the longest side in pixels — capping a 4000px-wide phone photo down to 1920px is usually the single biggest size saver, since almost no screen or catalog listing needs anything close to full camera resolution.
See exactly how much you saved, per photo and in total
Every compressed photo shows a clear before → after file size and percentage saved, plus a running total across the whole batch. Download each photo individually, or grab everything at once as a single ZIP file. Portrait photos taken with the phone held sideways are automatically corrected for orientation before compressing — Exif metadata is read and applied so a sideways photo always comes out upright, matching what you saw when you took it.
Your photos never leave your device
Compression happens entirely in your browser using the HTML canvas API — open your browser's network tab while using this tool and you'll see nothing fires when you compress a batch. That matters for unreleased product shots or anything you'd rather not upload to a random website just to make it smaller. Need to change the file format too (WebP to JPG, or resize to an exact preset like an Instagram post or Google Business Profile photo)? Use the companion Image Converter & Resizer tool.
Once your photos are compressed, a BizGo digital business page gives you a free, fast-loading gallery to publish them alongside your services, WhatsApp button, and Google review link — all in one shareable page.
Frequently Asked Questions
Typically 70-90% smaller at the default 75% quality setting, especially for large phone-camera JPGs — a 4MB photo commonly compresses to under 1MB with no visible quality loss at normal viewing sizes.
No. Every photo is decoded and re-encoded entirely in your browser using JavaScript and the HTML canvas API — nothing is ever sent anywhere.
Up to 20 photos in one batch. They are processed one at a time to keep memory use bounded, even on a mid-range phone.
PNG is a lossless format, so canvas re-encoding alone barely changes its size — the max-dimension cap is what actually shrinks a PNG. For maximum PNG/photo compression, convert to JPG or WebP with the Image Converter tool.
Photos taken with the phone rotated are automatically corrected using their embedded orientation data before compressing, so the output always comes out upright.
