To post several images at once, tap the multi-select icon before choosing. On a computer, photos can be posted to the feed from a desktop browser at instagram.com using the Create button. ## How to upload a photo to Instagram 1. Open the create screen: Tap the plus icon in the top or bottom bar and choose Post. Instagram asks for photo library access the first time. 2. Choose your images: Tap a photo to select it. For a carousel, tap the layered multi-select icon first, then tap images in the order you want them shown. 3. Crop and edit: Pinch or tap the expand arrows to set the crop, then pick a filter or use Edit for brightness, contrast and straightening. Edits apply per image in a carousel. 4. Write the caption and tags: Add the caption, tag accounts, set a location, and open advanced settings if you want alt text — you can write your own alt text under advanced settings before posting, and change it after publishing. 5. Share it: Tap Share to publish. If you are not ready, back out and choose Save as draft instead: an unfinished post can be saved as a draft from the caption screen and reopened later from the create menu. ## Posting one photo The single-image flow is the default, and the only decision that really matters is the crop — it determines how much of the frame survives in the feed and in your grid. Leave room around the subject; a photo composed edge to edge always loses something. ## Posting several photos as a carousel You are not limited to one image: one post can hold up to 20 photos and videos as a single swipeable carousel rather than one image. Tap the multi-select icon on the picker and the order you tap in becomes the order people swipe through, so choose the strongest frame first — most people never reach the last slide. Carousels also get a second look that single images never do: a carousel is often served again to someone who did not swipe, opening on the second slide. That is a large part of why they out-perform single images built from the same photos. ## Aspect ratio and image quality the feed supports aspect ratios between 1.91:1 and 3:4, and anything outside that range is cropped to fit. Portrait fills the most screen on a phone, which is why most creators shoot vertical and crop down rather than up. On quality: Instagram caps shared photos at 1080 pixels wide, sizing higher-resolution uploads down and enlarging anything under 320 pixels. Exporting a huge file does not help, and can hurt — a clean, correctly sized export usually beats an oversized one that gets squeezed. | Crop | Best for | |-|-| | Portrait | Feed reach — takes up the most vertical screen space | | Square | Grid consistency and predictable framing | | Landscape | Wide scenes, group shots, product lay-flats | ## Uploading from a computer Instagram is not phone-only: photos can be posted to the feed from a desktop browser at instagram.com using the Create button. Click Create, drag your file in, crop, add the caption, and post — the sane route when your photos live on a laptop. The trade-off is the editor. some posting features, such as adding collaborators, are documented as unavailable when creating from a computer, so do the heavy editing in whatever tool you already use and treat the browser as an upload window rather than a darkroom. ## Fixing things after you post Most of a post stays editable: the caption, tags, location and alt text of a published post can be edited afterwards, so a typo is never a reason to delete and repost. What you cannot easily undo is the picture itself, because a published carousel can be reordered or have items removed, but images cannot be swapped out. Deleting and reposting also throws away the engagement the post has already collected and starts it over from zero, which is rarely worth it for a small caption fix. ## Verification Last verified: 2026-07-28. Platform behaviour changes frequently; claims that had not been re-checked on that date are marked unverified on the HTML page. ## How do you upload multiple pictures to one Instagram post? Tap the multi-select icon in the photo picker, then tap each image in the order you want it to appear — one post can hold up to 20 photos and videos as a single swipeable carousel rather than one image. ## Can you upload photos to Instagram from a computer? Yes — photos can be posted to the feed from a desktop browser at instagram.com using the Create button. Bear in mind that some posting features, such as adding collaborators, are documented as unavailable when creating from a computer, so finish your editing first. ## What size should an Instagram photo be? the feed supports aspect ratios between 1.91:1 and 3:4, and anything outside that range is cropped to fit. Portrait takes up the most screen on a phone. Export at a sensible size rather than the largest possible file. ## Why does my photo look blurry after posting? Almost always compression plus scaling: Instagram caps shared photos at 1080 pixels wide, sizing higher-resolution uploads down and enlarging anything under 320 pixels. Export at the ratio you intend to post, avoid screenshots of screenshots, and avoid re-editing an already compressed file. ## Can I change the photo in a post after publishing? Not usually — a published carousel can be reordered or have items removed, but images cannot be swapped out. You can still fix the wording, because the caption, tags, location and alt text of a published post can be edited afterwards. ## How do I save an Instagram post to finish later? Use a draft: an unfinished post can be saved as a draft from the caption screen and reopened later from the create menu. Drafts keep your crop, filters and caption exactly as you left them. ## Should I add alt text? Yes — you can write your own alt text under advanced settings before posting, and change it after publishing. It makes the post usable with a screen reader and gives the image a plain-language description. ## Relevant links - [Instagram guides](https://bolta.ai/guides/instagram) - [All platform guides](https://bolta.ai/guides) - [reels length](https://bolta.ai/guides/instagram/reels-length) - [collab posts](https://bolta.ai/guides/instagram/collab-posts) - [close friends](https://bolta.ai/guides/instagram/close-friends)
