About SVG Formatter
SVG Formatter is a developer tool that runs in your browser. Format and indent SVG code with consistent 2-space indentation for readability. The page you are reading is the same workspace you will use to do the work: pick a file or paste your input, choose the options that matter to you, and the tool produces the result on your device.
If you fit any of these descriptions, SVG Formatter should slot cleanly into your workflow: devops engineers crafting one-liners; QA engineers writing repro cases; data analysts wrangling JSON. The tool keeps the controls focused on what matters for each of these use cases.
SVG Formatter parses your file with standard browser APIs entirely inside the browser, applies the options you selected, and returns a download. The processing has no network step, which means a slow or intermittent connection does not slow down the work — once the page is loaded, only your CPU and RAM are involved.
Behind the controls you see, standard browser APIs is doing the actual developer utility. Formats are detected on load and the engine produces a deterministic output for any given input + options combination — useful when you need to re-run a job and expect identical results.
Most people land on SVG Formatter via a search at the moment they actually need the tool. That shapes the design: the page is a single screen with the input on one side, the controls in the middle, and the result on the other, so a first-time visitor can complete the job without reading documentation.
Workflow tip: SVG Formatter pairs well with SVG Minifier and SVG Optimizer. Other adjacent tools you may find useful are SVG to JSX and SVG to React Component. Because every tool is a separate page, you can mix and match the steps that match your job. Bookmark the ones you reach for the most.
The output handed back by SVG Formatter is the output file. If you would prefer to keep the result in the browser instead of downloading it, you can copy it from the result panel and paste it directly into another tab — useful when the next tool in your workflow expects pasted text rather than a file.
The only practical limit is the 0 MB per-file ceiling, which keeps the tool responsive across a wide range of devices. Run the tool ten times in a row, run it ten thousand times — it behaves the same way and produces the same quality of result.
The transformation in SVG Formatter is deterministic — the same input plus the same options produces the same result every run. That predictability matters when the result has to match an upstream specification or be reproducible later.
A short note on how SVG Formatter came to look the way it does: every iteration started by watching how someone unfamiliar with the tool actually used it, then removing whatever got in their way. That is why the upload area dominates the screen, the run button is bigger than the secondary controls, and the result panel is unmissable when the job finishes.
A few practical tips that experienced users of SVG Formatter pick up over time. First, keep your default browser updated — the engine relies on standard web APIs and newer browser versions are noticeably faster than ones from a few years ago. Second, close other heavy tabs before processing a large input; the engine shares CPU and memory with whatever else is open. Third, if you re-run the same kind of job often, your last-used settings are remembered for the rest of the tab session, so subsequent runs are essentially one click.
If SVG Formatter appears to hang, the engine is almost certainly still working — large inputs simply take longer to process inside a browser than they would on a server with multi-core scheduling. For inputs near the 0 MB cap, give it up to a minute on a typical laptop before assuming something is stuck.
If you also use a command-line tool for svg formatter, SVG Formatter is a convenient alternative for the times you are on a different machine or helping someone who is not comfortable in a terminal. The output is a standard file in the format documented above.
SVG Formatter is intentionally narrow in scope so the common case is fast and the result is predictable. If you ever need a variation it does not cover, browse the rest of the catalog — there is a good chance an adjacent tool already exists, and switching between tools is just a matter of opening another tab.
How it works
- 1Reach the SVG Formatter page in your browser to begin.
- 2Drop a developer file onto the upload area, or click to pick one from your device.
- 3Pick any non-default settings you need. Most users leave the defaults alone for the first run and only revisit if the result needs tuning.
- 4Hit the run button. standard browser APIs does the work in your browser tab.
- 5Grab the output as soon as the run completes. You can also copy the result instead of downloading if the next tool in your workflow accepts pasted input.
- 6Repeat the process for additional inputs whenever you need to. The page stays loaded, so subsequent runs are quick.
Common use cases
- Inspect a regex against a test string before committing it using SVG Formatter.
- Format a noisy log line into something a teammate can read.
- Pretty-print a minified blob during incident triage.
- Validate a config blob before pushing to staging.
- Hash a string for a quick reproducibility check.
- Convert between data formats while wiring up an integration.
- Inspect a payload during local development without writing a script.
- Generate boilerplate from a single specification line.
- Generate a quick fixture without leaving the browser.
FAQ
Indentation style?
Uses 2-space indentation. Modify the output if you prefer different spacing.
Does it validate?
No — it reformats the markup without checking for SVG validity.
Inline styles?
Inline style attributes are preserved as-is during formatting.
Private?
Yes — formatting runs locally.
Large SVGs?
Very large SVGs may format slowly; the tool handles typical icon and illustration sizes well.
Namespace handling?
XML namespaces and attributes are preserved during formatting.
Are jobs run with SVG Formatter stored anywhere?
Favtoo keeps no copy of your file because Favtoo never receives your file. SVG Formatter runs entirely in your browser, the input is held only in your tab's memory, and closing the tab discards it. There is no opt-in cloud history, no "recent jobs" panel synced to an account, and no server-side retention to configure — the architecture simply has nowhere for your file to be stored.
Will SVG Formatter ask me to pay to download the result?
SVG Formatter is free to use. The processing runs in your browser, which keeps the per-user cost low enough that the tool can be offered openly. The download is the same file the engine produced — you can use it for as many runs as you need.
Does SVG Formatter work with screen readers?
SVG Formatter uses native HTML controls wherever possible, which means keyboard navigation, focus rings, and screen-reader labels work the way the platform expects. The drop zone accepts files via the keyboard-accessible file picker as well as drag-and-drop, and result downloads use standard browser download flows. If you spot an accessibility gap, Favtoo treats it as a bug worth fixing.
What should I do if SVG Formatter fails on my file?
Failures usually fall into one of three buckets: the input is in an unsupported format, the input is over the size cap, or the input is structurally malformed (a truncated download, a partial export, or a stream the engine does not recognise). The first two are easy to confirm — check that your file is in a supported format and that it is below 0 MB. For the third, opening the file in its native viewer first is the fastest way to confirm the source is intact.
How fast is SVG Formatter?
Most jobs finish in seconds. Speed scales with input size and with how many CPU cycles your browser tab has available — the engine runs in your browser, so it shares resources with whatever else you have open. For inputs near the 0 MB ceiling, expect anywhere from a few seconds to roughly a minute on a typical laptop. Closing other heavy tabs noticeably speeds things up.
Can I call SVG Formatter from a script?
SVG Formatter is a browser-only tool by design and does not expose a hosted API. The reason is the same as the privacy story: there is no Favtoo backend doing the work, so there is no service to call. If you need to script the same transformation, the underlying engine (standard browser APIs) is open-source and can be used directly from your own code.
Can I use SVG Formatter for commercial work?
SVG Formatter can be used for personal and commercial work alike — there is no separate "business" licence to purchase. The output you generate is yours to use however you want, including in client deliverables, internal documents, or commercial products. Favtoo's only ask is fair, individual use; the tool is not designed to be embedded as a backend service or wrapped behind an API for resale.
Will SVG Formatter keep working in a year?
SVG Formatter is updated whenever the underlying engine releases an improvement or a bug fix. Because the tool is delivered as a static page, every visit fetches the latest version automatically — there is no "version" to manage on your end. If a particular release ever changes default behaviour, the change is documented on Favtoo's changelog so you can confirm what shifted.
How do I run SVG Formatter over a folder of files?
SVG Formatter processes one input at a time by design — it keeps memory usage predictable on lower-end devices and makes results easier to verify. To handle a folder, run the tool once per file; the page stays loaded between runs and remembers your last-used settings, so the second run is essentially instant.
