Shrink JPG, PNG, WebP, GIF, and iPhone HEIC right in the browser. Quality slider with live size readout — you see immediately how much smaller the file gets. Sweet-spot 75% typically delivers 60–80% savings without any visible quality drop.
Drop an image, set quality, save compressed.

Clean trade-offs between quality and size — with the full control other tools skip.
10 to 100 percent, in 5% steps. Plus quick-pick buttons for the common scenarios: Email (60%), WhatsApp (70%), Web (75%), Social media (85%), Print (92%). Instead of blindly choosing 80%, you make a platform-aware decision.
A 4K photo at 4032×3024 will never display at full resolution on a web page. Reduce width to 1200 or 1920 px — at modern JPEG quality that often saves more than the quality slider. Presets for WhatsApp (640), Instagram (1080), Web (1200), Full HD (1920).
After compression you see immediately: old size, new size, percent saved. For web/email images that's the key info — no guessing, no opening the result to compare.
The compressed image appears directly on the page. Still looks good at 70%? Or better 80%? Slide back, compress again — no repeated file downloads to compare.
Family photos, headshots, ID scans, intimate captures — everything stays in the browser. Re-encoding via Canvas removes EXIF (incl. GPS) automatically, strengthening privacy. No cloud, no third-party processing.
Other online tools upload your image to a server, compress, and return — that's two full file transfers for a 10 MB file. Here everything happens locally in milliseconds. Even a 50 MB RAW can be reduced without burning mobile data.
Three steps, three seconds.
Drag-and-drop or file dialog. JPG, PNG, WebP, GIF, and iPhone HEIC all accepted.
Slider or quick-pick button for your use case. Optional pixel-width adjustment.

Where image compression really matters day to day.
Images are the #1 performance hog in 90% of websites. Going from 3 MB to 250 KB on a hero image often pulls LCP (Largest Contentful Paint) from 4s down to under 2s — Google PageSpeed green. Directly visible in Core Web Vitals.
Gmail, Outlook, Yahoo Mail cap attachments at 20–25 MB. iPhone application photos and product shots easily hit 5 MB each. At 75% quality + 1200 px most photos drop to 200–500 KB — fits any email.
WhatsApp auto-compresses photos to roughly 800 px at 50% quality — sometimes they look terrible. Pre-compressing in controlled way (1080 px at 75%) and sending "As Document" or directly keeps the better quality.
Fast product pages sell more. Instead of uploading every 8 MP DSLR product photo, pre-compress to 1500 px at 80% — your inventory updates 3× faster and the store loads noticeably snappier.
Featured images, inline graphics, newsletter headers — 5–10 images per post adds up to hundreds of MB a year. Cutting to 200 KB per image saves storage and CDN bills measurably.
Academic papers with embedded photo or screenshot figures balloon to 30–50 MB and blow past LMS upload limits (Canvas, Blackboard, Brightspace). Pre-compress images — paper comfortably below the cap.
Web and social media: 75–80% — the proven sweet spot, barely visible loss, file usually 60–80% smaller. Print: at least 90%. WhatsApp/Telegram: 65–70% is enough. Headshots/portraits: 85% to keep skin tones clean.
Yes. A JPG stays JPG, a PNG stays PNG, a WebP stays WebP. To change format (e.g. PNG to JPG for smaller files), use our separate PNG-to-JPG or Image-to-WebP tools.
PNGs are already lossless-compressed, so savings are smaller than JPGs. Typically 20–40% by reducing bit depth, optimizing the palette, and removing metadata chunks. For photos in PNG form savings are bigger.
Yes, automatically. Re-encoding via the Canvas API drops all EXIF metadata — camera model, capture date, GPS coordinates, exposure time. That's usually wanted for web/social uploads (privacy).
Yes. iPhone HEIC photos are decoded automatically in the browser (Safari, modern Chrome and Firefox) and can then be compressed. To get the result as JPG, use our JPG converter additionally.

No. Compression runs via the Canvas API directly in your browser — a built-in feature every modern browser provides natively. No server roundtrip, no logs, no tracking. Especially important for private photos and ID scans.
Directly — smaller images mean better LCP and a lower CLS score. For PageSpeed Insights keep images under 200 KB — usually reachable with 75% quality at 1920px max width.
Images are the #1 performance bottleneck in 90% of websites. A single uncompressed iPhone photo can hit 5–8 MB — that's 30 seconds of load time over mobile. At the same time the human eye is surprisingly tolerant with modern JPEG compression: between 75% and 100% quality there's barely a visible difference on normal photo content, but drastically different file sizes. Our online compressor makes that sweet spot tangible via a slider — directly in the browser, no upload, with live preview.
We load the image into an HTML5 canvas element, optionally rescale it to a smaller pixel width, and then call the browser's canvas.toDataURL(format, quality) method. That method is built into Chrome, Safari, Firefox, and Edge and uses the OS's native JPEG/PNG encoders — faster than any JavaScript library and producing results virtually identical to Photoshop's "Save for Web". The compressed image is displayed as a data URL in the preview and offered as a Blob for download.
The right quality is use-case-specific: for print don't go below 90% — otherwise skin tones get blotchy and fine details smear. For web 75–80% is the classic, because JPEG artifacts are basically imperceptible on normal photo content while file size drops 60–80%. For WhatsApp and smartphone delivery 65–70% is enough because recipient displays don't show finer detail anyway. Our quick-pick buttons set the right level with one click.
A modern iPhone photo is 4032 × 3024 pixels. A web page displays it at 800–1200 pixels wide. The extra pixels get downsampled by the browser anyway — they only cost storage and bandwidth. Our tool offers a pixel-width slider with platform presets: WhatsApp (640), Instagram (1080), standard web (1200), Full HD (1920). Resizing alone often delivers more than quality — and combined, 90% savings without visible loss is realistic.
iPhone, Android, and DSLR photos carry EXIF metadata: camera model, focal length, exposure time, ISO, and crucially GPS coordinates. Uploading personal photos to social media or sending via email can be problematic — the capture location ships with the file. Our compressor removes EXIF automatically because the Canvas API doesn't carry the EXIF block during re-encoding. Privacy bonus.
Since 2021 Google treats Core Web Vitals (LCP, FID, CLS) as ranking factors. LCP (Largest Contentful Paint) — usually the hero image — should stay under 2.5 seconds. With a 3 MB image on 4G that's impossible. At 200 KB it's easy. Direct SEO outcome: better Core Web Vitals → better ranking. Our tool is therefore not just a UX utility but a direct SEO measure.
Family photos, headshots, ID scans, diagnostic images for medical second opinions — all very personal content. Pushing them through a free cloud compressor abroad is GDPR-risky. BrowserCrunch processes purely in your browser. Bonus: works offline once the page is loaded — test it: open browser tab → airplane mode → drop image → still works.
