An Instant Image Slideshow is a browser-based tool that lets you play local photos as a smooth, auto-advancing slideshow — without uploading anything to a server. Simply select images from your device, and they play instantly in a beautiful viewer with customizable transitions, speed control, and fullscreen support. Perfect for quick photo reviews, presentations, or enjoying memories.

No — never. This tool runs entirely in your browser. All images are loaded as local object URLs (blob URLs) and never leave your device. There is zero data transmission, no cloud storage, and no tracking. Your privacy is 100% guaranteed. You can even disconnect from the internet after the page loads and it will continue working.

The tool supports all common image formats: JPG/JPEG, PNG, GIF (static first frame), WebP, SVG, BMP, and TIFF (browser-dependent). As long as your browser can display the image, the slideshow can play it. For animated GIFs, the slideshow displays them as static frames.

You have three easy ways to add images:
1️⃣ Click the viewer area to open your file picker.
2️⃣ Drag & drop images directly onto the viewer from your file explorer.
3️⃣ Click the "Add" button below the viewer to select more images without clearing existing ones. All methods support selecting multiple files at once.

Yes! Choose from three transition styles:
🎬 Fade — A smooth crossfade between images (default, most elegant).
🔄 Slide — Images slide horizontally, giving a cinematic feel.
⚡ Instant — No transition; images swap immediately. Great for fast browsing. You can switch transitions anytime, even during playback.

Use the speed slider (clock icon) in the control bar. You can set the duration each slide stays visible from 1 second to 10 seconds, in 0.5-second increments. The default is 3 seconds. The current speed is displayed next to the slider and updates in real time — even during playback.

Absolutely. Click the Fullscreen button (expand icon) or press the F key on your keyboard. The viewer expands to fill your entire screen — perfect for presentations or immersive photo viewing. Press Escape or click the button again to exit fullscreen mode.

Yes! The slideshow is fully responsive and works great on iOS and Android devices. You can tap to select images from your photo library, swipe left/right on the viewer to navigate between slides, and use all controls optimized for touch. The thumbnail strip scrolls horizontally with touch gestures.

Power users will love these shortcuts:
← Left Arrow — Previous slide
→ Right Arrow — Next slide
Spacebar — Play / Pause toggle
F key — Toggle fullscreen
Escape — Exit fullscreen
All shortcuts work instantly and don't interfere with other page elements when the viewer is focused.

Yes, 100% free. No sign-ups, no subscriptions, no hidden fees, no ads. It's a fully functional local photo player that respects your privacy and works offline. Share it with friends, use it for work, embed it — no restrictions.

There is no hard limit. You can add as many images as your device's memory can handle. The tool creates lightweight object URLs and only renders the visible slide plus thumbnails. For best performance on most devices, we recommend up to 500 images per session, but many users successfully load 1,000+ photos.

Nothing is stored. When you close the tab or browser, all object URLs are revoked and the image data is cleared from memory. There is no persistence, no cache, and no local storage of your images. Each visit starts fresh — this is by design to protect your privacy.

Yes! The Loop toggle (enabled by default) makes the slideshow wrap around from the last image back to the first, creating an endless playback loop. When loop is turned off, the slideshow stops automatically after the last image. You can toggle this setting anytime.

Unlike cloud-based slideshow makers, this tool:
✅ Never uploads your photos — everything stays local.
✅ Works instantly — no rendering or processing wait time.
✅ Requires no account — just open and use.
✅ Works offline — no internet needed after initial page load.
✅ Respects privacy — zero tracking, zero ads.
It's designed for speed, simplicity, and privacy above all else.
