Convert images & files, entirely in your browser
Free converters for HEIC, AVIF, WebP, PNG, JPG, GIF, ICO and PDF. Your files are never uploaded; every conversion runs on your own device. Need conversions to happen automatically inside a Zapier, Make, or n8n workflow, or your own code? Add one call to the REST API.
The API in action
Nearly every converter on this page is also a REST endpoint. Here is what that looks like in practice: one HTTP call turns the wrong format into the right one, wherever your files move.
Animated demo: platforms like Airtable and Shopify send image files to the formatably REST API, which converts them and returns the converted file to the next step of a workflow, script, or backend.
IMG_0284.heic 3.1 MB · HEIC
IMG_0284.jpg 1.8 MB · JPEG
Add one HTTP step to any workflow. No code.

Common fixes
The files these converters fix usually come from somewhere. Here is where people reach for formatably most, and the converters that fit each job.
iPhone and iPad photos
iOS saves photos as HEIC, which Windows, older Android phones, and most upload forms cannot open.
Images saved from the web
Right-click-save on a modern site often gives you WebP or AVIF, even when the page showed a JPG. Editors and forms frequently reject both.
Picky upload forms
Government portals, job applications, and listing sites often demand an exact extension like .jpg and reject everything else.
Paperwork and printing
Receipts, IDs, contracts, and whiteboard photos are easier to email, print, and archive as a single PDF.
Your own website
Browsers want a favicon in ICO format, and pages load faster when heavy PNG and JPG images are served as WebP, whether you run WordPress, Shopify, or hand-built pages.
Design and editing
Pull individual pages out of a PDF as images, or move screenshots into formats that keep transparency.
Frequently asked questions
Are the converters really free?
Yes. Every browser converter on the site is free with no signup, no account, no watermarks, and no usage cap. The only paid product is the REST API, for when you need the same conversions to run automatically inside an automation workflow or your own code.
Are my files uploaded to a server?
No. Every converter runs inside your own browser tab using WebAssembly and the canvas API, with no ads on the page. Your photos and documents are never uploaded, logged, or stored on our servers, and you can verify that yourself: open your browser's developer tools and watch the Network tab while you convert (no requests leave the page), or go offline after the page loads and keep converting.
Which formats can I convert?
HEIC and HEIF photos from iPhones, AVIF and WebP images from the web, plus PNG, JPG, JPEG, JFIF, and GIF. You can also turn images into PDFs, pull PDF pages out as images, and build a multi-size ICO favicon from a PNG. Every converter supports batch conversion with a zip download.
Do I need to create an account?
Not for the browser converters. You only create a lightweight account (via a one-time email sign-in link, no password) if you subscribe to the API, so you can retrieve your API key and manage billing.
Can I convert files automatically in Zapier, Make, n8n, or my own code?
Yes. The converters are also REST endpoints: POST the file bytes, get the converted file straight back. That makes it a drop-in step in no-code automation tools (add an HTTP request in Zapier, Make, or n8n with your key in the X-Api-Key header) as well as in scripts, cron jobs, and backends. Anonymous calls are capped at 25 per day; a paid API key removes the limit.
Is there a file size limit?
In the browser there is no hard limit; you are bounded only by your device's memory, and files of a few hundred megabytes are usually fine. The API accepts up to 4 MB in a direct request, or up to 100 MB per file using the large-file upload flow described in the API docs.
Will converting reduce image quality?
Conversions to PNG, ICO, and PDF are lossless: the pixels are stored exactly as decoded. Conversions to JPG and WebP re-encode at a high quality setting (92% and 90%) chosen so that photos look identical to the original while staying small. GIF output is limited to 256 colors by the format itself.
About formatably
formatably is a collection of 20 focused converters for the image and file formats people run into every day. Turn an iPhone HEIC photo into a JPG that Windows can open, convert a WebP or AVIF saved from the web into a normal image, combine photos into a single PDF, pull PDF pages out as images, or build a proper multi-size ICO favicon from a PNG. Each conversion has its own dedicated page with a drag-and-drop converter, batch support, and instant downloads.
The defining choice behind formatablyis that everything happens on your own device. Unlike converter sites that upload your file to a server, these tools decode and re-encode images with WebAssembly and the canvas API running in your browser. That matters when the thing you are converting is a photo of your ID, a signed contract, a medical document, or family pictures that should never sit on someone else's server. It also means there are no queues, no per-day conversion caps, and no waiting on uploads: a 50 MB file converts as fast as your machine can decode it.
When you need the same conversions outside the browser, the REST API exposes the converters as endpoints you can call from an automation tool like Zapier, Make, or n8n, or from a script, a cron job, or a backend service, with a large-file flow for uploads up to 100 MB. The browser converters stay free forever; the API subscription is what keeps the project running. See pricing for details.
