Instagram posts come in three formats: a single photo, a single video, or a carousel of up to 10 mixed media items (photos and videos together). All three are accessible through the same /p/<shortcode> URL structure on Instagram. FastDL App's post downloader auto-detects which format you have pasted and gives you the appropriate download options.
For single-photo posts, you get one JPG at full resolution (typically 1080×1350 for portrait, 1080×1080 for square, or 1080×566 for landscape). For single-video posts (not Reels, not IGTV — these are the older in-feed videos), you get one MP4 in HD with original audio. For carousel posts, you get a list of every item in the carousel, each with its own download button, plus a one-click "Download All" button.
Photos are saved at the largest resolution Instagram has stored for that post. Instagram does downscale uploads — for example, if you upload a 4000×5000 photo, Instagram stores it as 1080×1350. FastDL App delivers that 1080×1350 version, which is the largest available. We do not upscale, because upscaling adds no real detail and just bloats the file size.
How to download Instagram photos in full resolution
Instagram deliberately shows photos at a smaller resolution inside the app and on the web — usually 600×750 in the feed, expanding to 1080×1350 only when you tap to enlarge. But the original 1080×1350 file is what gets stored on Instagram's CDN, and that is exactly what FastDL App retrieves. Here is the step-by-step:
- Step 1 — Copy the post URL: In the Instagram app, tap the three dots (•••) above the post and choose "Copy link". On the web, copy the URL from the browser address bar (it looks like instagram.com/p/CxYz12345/).
- Step 2 — Paste on FastDL App: Open fastdlapp.pro/posts (this page) and paste the URL into the input box above. The tool auto-detects that it's a post.
- Step 3 — Press Download: FastDL App fetches the original media from Instagram's CDN in under a second. For carousels, every item appears as a separate thumbnail.
- Step 4 — Save the file(s): Click Download next to each item you want. For carousels, hit "Download All" to grab every item in one click. Files save to your device's Downloads folder (or Photos app on iOS).
Carousel posts: download all 10 items at once
Carousel posts let creators upload up to 10 photos or videos in a single post. Saving them one-by-one inside Instagram is painful — and the app does not even offer a "save all" option. FastDL App's carousel downloader solves this. Paste the post URL, and you get a grid of every item in the carousel, each with its own download button. A "Download All" button at the top queues every item for download, usually completing in under 5 seconds for a 10-item carousel.
Each item is delivered in its original format and resolution — photos as JPGs at 1080×1350 (or square 1080×1080, or landscape 1080×566, depending on how the creator uploaded them), videos as HD MP4s with original AAC audio. We do not mix formats, do not convert videos to GIFs, and do not strip metadata. The files you download are the files the creator uploaded.
For carousel posts with mixed photos and videos, FastDL App detects each item's type automatically and labels it ("JPG" or "MP4" badge in the top-right of each thumbnail). You can choose to download only the videos, only the photos, or everything — the choice is yours.
Quality, watermark, and what you actually get
When you download a post through FastDL App, you get the original media file — no FastDL watermark, no recompression, no re-encoding. Photos are saved as JPGs at the resolution Instagram stores (typically 1080×1350). Videos are saved as MP4s in HD (typically 1080p vertical or 1080p square) with the original AAC audio track at 128 kbps.
The file you download is the file the creator uploaded — we never modify it. This means if the creator uploaded a heavily-compressed photo with visible JPEG artifacts, your downloaded copy will also have those artifacts. We do not apply any enhancement, upscaling, or noise reduction. What you see is what you get.
For researchers, journalists and archivists, this matters. The file you save through FastDL App is forensically identical to the file stored on Instagram's CDN. You can use it as primary source material, compare it against other archives, or verify its authenticity using standard tools.
