HEIC conversion, batch resizing, compression — all in mobile Safari. No app to install, no signup, no upload. Built for iPhone photographers.
Modern iPhones take great photos. They also take photos in HEIC format that don't open on Windows, are 48 megapixels (way too big for most uses), and carry GPS metadata you might not want to share.
pictoolkit's tools solve all of this directly in mobile Safari — no app install, no upload, nothing leaves your phone.
The most common iPhone image task. Send a photo to a Windows user, upload to a website that rejects HEIC, share with someone on an older Android phone — you need JPG.
Our HEIC converter works in mobile Safari. Tap the dropzone, pick photos from your library, download JPGs. The conversion happens on your phone.
iPhone 14 Pro and newer can take 48 megapixel photos. A single one might be 8 MB. Email clients reject anything over 25 MB, and even at 5 MB each, photos take forever to upload to many services.
Our compressor reduces these to 200-500 KB with no visible quality loss. Batch multiple at once.
iPhone photos contain GPS coordinates of where they were taken. Share a photo from your home and you're sharing your home address with whoever sees the file. Our upcoming EXIF viewer shows what's in your file and lets you strip it.
iPhone photos are huge. Social media platforms downsize them anyway, but you can pre-control the dimensions for predictable cropping. Our resize tool has presets for Instagram square (1080×1080), Instagram story (1080×1920), and other social formats.
If you upload iPhone photos to your blog or website, WebP gives you 25-35% smaller files than JPG. Better page performance, no quality difference.
Some image tools require you to install an app. We deliberately don't — the tools work in your phone's browser. This is faster (no install), more private (no app permissions), and uses no storage on your phone.
The trade-off is that mobile processing is slower than on a laptop. Photos take a few extra seconds to process. For most users, that's a fair price for not installing yet another app.
You can change iPhone to use JPG instead of HEIC at Settings → Camera → Formats → "Most Compatible."
Pros: Every photo works everywhere immediately. No conversion needed.
Cons: You lose 30-50% storage efficiency. Multi-photo features (Live Photos, depth maps) may behave differently.
Our recommendation: keep HEIC as default for storage benefits, convert when you actually need to share with non-Apple users.
For sharing 1-2 photos with someone on Windows: open our HEIC converter in Safari, drop the photos, download, share.
If you want to back up your iPhone photos as JPGs (so they're readable on any future computer), batch convert via our HEIC tool. Process hundreds at once.
Post iPhone photos to your blog: convert HEIC to JPG → resize to display width → compress quality 85 in WebP. All in Safari.
Photograph the item, convert to JPG, resize to platform recommendations, strip EXIF (so buyers don't see your home GPS), upload listing.
iPhone photos contain a lot of metadata that most people don't realize:
For most casual sharing this is harmless. For more sensitive contexts (selling items publicly, social media, dating profiles), strip the metadata first.
