Image converter — change any image format in your browser

Image ConverterPublished July 2, 20267 min read

To change an image format, open the free image converter, drop your file, pick the target format — PNG, JPG, WebP or AVIF — and download the result. The whole conversion runs inside your browser: your image is never uploaded to any server.

That covers a lot of ground. Carbide reads ten formats (PNG, JPG, WebP, AVIF, HEIC, GIF, BMP, SVG, TIFF and ICO) and has a dedicated page for each of the 27 most-searched pairs, from PNG to JPG to HEIC to JPG. Here is how it works, what really happens to transparency and quality, and which format to pick for each job.

How in-browser conversion works — nothing is uploaded

Most converter sites take your file, send it to their server, convert it there and hand back a download link. Carbide's image converter skips the round trip: your browser decodes the image, redraws it onto a canvas, and re-encodes it in the format you chose — all on your own device. Because nothing is uploaded, there is nothing to retain, leak or rate-limit, which is exactly what you want for personal photos, ID scans and client work.

The steps are the same for every format pair:

  • Open the image converter — or jump straight to a pair page like PNG to JPG.
  • Drop your image, or tap to pick one — it works the same on your phone.
  • Choose the target format: PNG, JPG, WebP or AVIF.
  • For lossy targets, set the quality slider; PNG needs no slider — it is lossless.
  • Download. You get the same image with the new extension, instantly — no queue, no email, no watermark.

PNG to JPG — what happens to transparency and quality

The two questions people ask most about PNG to JPG deserve straight answers. First, transparency: JPG has no alpha channel, so any transparent areas in your PNG are filled with a solid white background. If your logo or cut-out needs to stay transparent, keep it as PNG — or convert it to WebP, which supports transparency at a fraction of the size.

Second, quality: JPG is a lossy format, so converting does discard some data. At the default quality you will rarely see a difference in a photo, and the file often shrinks dramatically — which is the whole point when you need to email a picture, upload it to a form with a size cap, or share it in a chat. Use the quality slider to choose your trade-off: higher for prints, lower for quick shares. The result to expect: a much smaller .jpg that looks the same at normal viewing size.

JPG to PNG — it stops further loss, but adds nothing back

Converting JPG to PNG is useful, but for different reasons than most people expect. PNG is lossless, so once your image is a PNG it will not degrade again no matter how many times it is saved — that makes it the right base for repeated editing, annotation or archiving. What the conversion cannot do is recover detail: the data JPG compression already discarded is gone, and a PNG copy looks exactly like the JPG it came from.

It also does not make the background transparent — a JPG has no transparency to reveal, so the PNG keeps the same solid background. If a transparent background is what you actually want, run the photo through the Background Remover and export a transparent PNG from there, or clean it up first in the image editor. Convert to PNG before you edit; convert to JPG after you finish, when it is time to share.

The full matrix — every from→to conversion, one click away

Beyond the core pair, every conversion has its own page, so you can bookmark exactly the one you need. The matrix reads ten formats and encodes to the four a browser can write — PNG, JPG, WebP and AVIF:

The quality slider — lossy vs lossless targets

The target format decides whether you see a quality slider. PNG is lossless: there is nothing to tune, and the output is a pixel-perfect copy — usually the largest file of the four. JPG, WebP and AVIF are lossy: the slider controls how aggressively they compress, trading file size against fine detail.

A practical default is 80–90%. Photos survive that range with no visible change, while the file often drops to a fraction of the original. Go higher when the image will be printed or zoomed; go lower for thumbnails and previews where size matters more than pixel-level fidelity. One habit worth keeping: avoid re-saving a lossy file through a lossy format repeatedly — each pass discards a little more. Convert once from the best original you have, and keep that original. If you are optimizing a whole site's images, PNG to WebP or PNG to AVIF at ~85% is the sweet spot for most pages.

Frequently asked questions

Is my image uploaded when I convert it?

No. The image converter decodes and re-encodes your image entirely in your browser using the canvas API. The file never leaves your device, which makes it safe for personal photos, IDs and confidential work.

How do I change an image format without installing software?

Open the image converter in any modern browser — on your computer or phone — drop the image, pick the new format and download. No install, no sign-up, no account.

Does converting PNG to JPG lose quality?

Slightly — JPG is a lossy format, so some data is discarded, and transparent areas are filled with white. At 80–90% quality the difference in a photo is rarely visible, and the file gets much smaller. Use PNG to JPG with the quality slider to pick your trade-off.

Which image formats are supported?

The converter reads PNG, JPG, WebP, AVIF, HEIC, GIF, BMP, SVG, TIFF and ICO, and exports to PNG, JPG, WebP and AVIF — the formats browsers can encode. Two honest notes: animated GIFs convert as their first frame, and multi-page TIFFs convert as their first page.

Is there a file size or daily limit?

No artificial limits. Because the conversion runs on your device, there is no server quota, no daily cap and no paid tier — the practical limit is your device's memory, which handles everyday photos comfortably. It is free, with no watermark on the output.

Changing an image format should take seconds, not a sign-up form and an upload queue. Open the image converter for any file, or go straight to PNG to JPG and JPG to PNG for the everyday pairs — free, private and entirely in your browser.
