Tips for consistent conversions

If you are using Base64 for CSS or HTML, remember that encoded content increases file size, so use it for small icons or inline assets. After converting, preview the output and verify color, transparency, and resolution. Files are processed only as long as needed and then removed.

Format decision cheat sheet

See image format cheat sheet: JPG for photographs, PNG for UI screenshots, WebP for web pages, HEIC for iPhone camera roll
Match the format to the task: photos, diagrams, web pages, or iPhone exports.

Before you start a conversion, match the output format to how the image will be used.

  • JPG - photographs that will be emailed, uploaded to a CMS, or shared across platforms. Lossy, small files, no transparency.
  • PNG - UI screenshots, diagrams, anything needing transparency, and anything you might edit again later. Lossless, larger files.
  • WebP - web pages where you control the audience and know modern browsers are in use. About 25-35% smaller than a matched-quality JPG or PNG, supports transparency.
  • HEIC - iPhone camera roll exports kept inside the Apple ecosystem. Skip when sharing with Windows, Android, or third-party CMSes.
  • SVG - logos, icons, illustrations, and anything that must scale to any size. Not suitable for photographs.

When in doubt, convert to JPG for photos and PNG for anything with sharp edges; you can re-convert later without reopening the source.

Other freetoolonline tools you might need

Image conversion is often one step inside a larger workflow. If you are preparing a document, you may also need to combine images into a PDF or compress an image first. For photographers exporting from an iPhone, pair this page with the PDF tools hub to ship deliverables as a single PDF. Developers using Base64 inline should cross-reference the developer tools hub for JSON parsing, CSS minification, and JavaScript minification. If you are preparing for a presentation or a video call after exporting your images, the device test tools hub covers camera, microphone, and screen checks.

Format-pair notes worth knowing before you convert

HEIC to JPG. The iPhone-default format that Windows, Android, and most CMSes still refuse: HEIC to JPG is the direct route.

SVG to PNG or WebP. Open SVG to PNG / WebP, pick a raster output, set the export size, and download. PNG keeps the transparent areas of the source SVG intact, so it is the right raster target when transparency matters; since SVG has no native pixel size, choose the export width that matches your destination before you download.

PNG to SVG. PNG to SVG by Interpolation Algorithm is genuinely lossy in shape: it traces the bitmap into a vector approximation rather than recovering the original geometry, so it works well for simple icons, logos, and high-contrast UI marks and less well for photographs or images with subtle gradients. Run the output through a visual review before shipping.

Image to Base64. Image To Base64 encodes a JPG, PNG, WebP, SVG, or HEIC into a string you can paste into inline CSS, a data URI in an HTML <img> tag, or a JSON payload; Base64 To Image decodes one back into a downloadable file. Watch the prefix header: copy the full data:image/png;base64,... string when the destination is a CSS or HTML embed, and copy only the payload after the comma when the destination is a JSON or programming-language literal.

Frequently Asked Questions

Which output format should I choose for a photo shared with anyone?

JPG is the safe universal pick. It opens on every OS and every email or chat client without a codec install. Use HEIC to JPG if your source is an iPhone photo, or SVG to PNG for vector artwork you need to flatten.

When does WebP make sense over JPG or PNG?

Use WebP when you control the destination and know modern browsers are in use (web pages, product galleries, apps). It typically ships 25-35% smaller than a matched-quality JPG or PNG and supports transparency. Skip WebP for email attachments or CMS uploads that still require JPG or PNG.

Will EXIF metadata survive the conversion?

On iPhone-era formats (HEIC) the EXIF block is preserved by default, so your timestamp, GPS, camera model, and lens data carry into the JPG. If you are sharing publicly and want to strip location or camera-ID data, toggle the EXIF option off in the tool's Settings before download.

Can I convert a screenshot to SVG?

Not meaningfully. SVG is for vectors; screenshots are pixels. PNG to SVG traces simple shapes, but complex UI or photos will not trace cleanly. For icons and logos, start from the original vector (Illustrator, Figma, or Inkscape) when you can.

What if I need to compress instead of convert?

See the Image Tools hub. Compress Image reduces file size without changing the format. The converter tools here change the format; the editing tools change the pixels.
