Tools

Free tools for the fiddly parts of social media

Cut a grid, split a carousel, see if a name is taken. No account needed, and the image tools never upload your photos.

Which tool do you need?

Each one does a single job. Start from what you're trying to make.

  • One picture across your whole profile

    Instagram Grid Maker. Cuts a photo into 3 to 18 posts that join back up on your profile grid. Each one is a full 1080×1350 JPG, numbered in the order you post it, saved one at a time or all together in a ZIP.

  • A wide picture people swipe through

    Instagram Carousel Splitter. Turns a panorama or any wide design into 2 to 10 portrait slides that meet edge to edge, so every swipe moves further along the same image.

  • A new Instagram username

    Instagram Handle Checker. Tidies a name down to what Instagram accepts (letters, numbers, periods and underscores, up to 30 characters), opens that profile so you can see whether it's taken, and offers up to 6 alternatives.

  • A new TikTok username

    TikTok Username Checker. Makes sure a name fits TikTok's rules (2 to 24 characters, no period at the end), opens its profile, and suggests up to four alternatives in case someone got there first.

  • A caption for a finished video

    TikTok Caption Generator. Describe the video, pick one of 12 tones and, if you like, say who it's for. AI writes one caption of up to 150 characters, and leaves the hashtags to you.

What happens to your photos and names

The two image tools do all their work inside your browser. Your picture is opened, cut and saved on your own device and is never uploaded to us, so there is nothing on our side to keep, look at or delete. The grid maker takes JPG, PNG or WebP files up to 4 MB, the carousel splitter up to 10 MB, and both save what they make as JPGs.

The username checkers never contact Instagram or TikTok. They build the address where a profile with that name would live and open it in a new tab, and you read the answer off the network's own page. That is also why the result is a strong hint rather than a promise: an account that was deactivated or banned, or a name someone gave up recently, can look free and still be unavailable. The final word is the app's, when you try to use the name.

The caption generator and the tag generator are the only tools that send anything to a server. What you type goes to an AI model, which writes the answer back. Every one of those is a paid call on our side, so each internet address gets a limited number an hour — and we keep what was typed, with the price of the call, so we can see what people are asking for. No account is attached to it, and what the model writes back is not kept. Everything else on this page happens in your own browser, and no picture you open ever reaches us — the image tools and the thumbnail preview are yours alone. We do keep a copy of the text typed into the others, up to 500 characters, so we can see what people use them for.

Why they cost nothing

No account, no card, no watermark on your images, and no limit on how many grids, carousels or name checks you run; the caption generator is the only one with a cap, for the reason above. We build iHatePosting, a social media scheduler, and these are the small jobs around posting that we think should never cost anything. If one saves you ten minutes, we hope you remember where it came from.

From a finished file to a scheduled post

Making the post is half the job; getting it out at the right time is the other half. iHatePosting schedules to Instagram and thirteen other networks from one composer:

Your first 90 days are free.

FAQ

Are these tools really free?

Yes. There's no account to create and nothing to pay, and the image tools and username checkers have no usage limit at all. The caption generator allows 20 captions an hour for each internet address, because every caption costs us an AI call.

Do you keep the pictures I use?

No. The grid maker and the carousel splitter never upload your picture: it's opened and cut in your browser, and the files are saved straight to your device. We never see it, and those two tools send us no text either — a picture is their whole input.

Why can't the username checkers just tell me a name is free?

Because they don't ask Instagram or TikTok anything. They open the profile page so you can see what's there. A profile means the name is taken; a missing one usually means it's free, but deactivated accounts and recently released names can look the same. Trying to set the name in the app is the only sure test.

Is there a watermark on the images?

No. Nothing is added to your picture: no logo, no stamp, no badge in the corner. The only extra in a grid tile is the background color you choose, and only where the picture doesn't reach.

What size should an Instagram post be?

For the feed, 1080×1350 pixels. That 4:5 portrait is the tallest shape Instagram shows in the feed, and it's what both image tools save. Your profile grid then shows only the middle 3:4 of each post, which is why the grid maker cuts its tiles for that view rather than side by side.

What's the difference between a grid and a carousel?

A grid is several separate posts that line up on your profile, so the whole picture appears when someone visits it. A carousel is a single post that people swipe through in their feed. The grid maker makes the first and the carousel splitter the second, and files cut for one don't work well as the other: grid tiles are numbered for your profile, bottom-right first.

In what order do I post grid tiles?

In filename order, image1.jpg first. Instagram puts each new post at the top left of your profile, so the tile you post first ends up at the bottom right once the rest are up. Post nothing else until the last tile is live, or the picture comes out scrambled.

How long can an Instagram or TikTok username be?

Instagram's limit is usually given as 30 characters and TikTok's as 24. Both allow letters, numbers, periods and underscores, and TikTok also refuses a period at the very end. Each checker holds a name to its network's rules as you type, and the TikTok one flags a period at the end under the box.

Does the caption generator write hashtags?

No. It's told to leave them out, so what comes back is the caption on its own. Add a few afterwards that describe the video, rather than whatever happens to be trending that day.

Do the image tools lower my picture's quality?

Very little. Grid tiles are saved as JPGs at 92% quality and carousel slides at 95%, both at the full 1080×1350. What softens a result is the source: a picture smaller than the grid or the slides is stretched to fill them, and stretched pixels look soft. Start from the biggest copy you have.

Which file types can I use?

JPG, PNG and WebP in both image tools, up to 4 MB in the grid maker and 10 MB in the carousel splitter. Everything comes out as a JPG, which has no transparency: see-through parts take on the background color you pick in the grid maker, and turn black in a carousel slide.

Can I use them for a business or client account?

Yes. Nothing here depends on the kind of account. The image tools work on files, and the checkers open public profile pages, which live at the same address for personal, creator and business accounts alike.

Do the tools work on a phone?

Yes. They're ordinary web pages, so there's nothing to install. The grid maker is built for touch as well as a mouse, and the carousel splitter's layout adapts to a small screen.
