HyperDAF Image Converter (2026): Convert JPG, PNG and WebP Online — Free, No Upload, No Sign-Up

What Is the HyperDAF Image Converter?

The HyperDAF Image Converter is a free online tool that converts images in your browser. You drop your files onto the page, pick an output format, set the quality and size, and download the results. There is nothing to install, no account to create and no sign-up form to fill in. It is a web tool, not a Chrome extension and not an app.

Open the free Image Converter and convert your first image now — no upload, no sign-up, up to 20 images at a time.

How It Works

The page lists four steps, and there is nothing hidden behind them:

1. Upload images — Drag and drop or browse your images.
2. Choose output format — Select the format you want to convert to.
3. Adjust settings — Quality, size, platform size, background and more.
4. Download — Preview and download your converted images.

You can add up to 20 images at a time, add more files to the same batch, or clear the batch and start again. When the batch is done, download each converted image on its own, or download them all at once as a ZIP file, and check the savings shown for each file.

Convert JPG to WebP — the Most Common Job

Converting JPG to WebP is the most common job this tool does, and it is also the easiest way to make a page faster: WebP files are usually much smaller than the JPGs they replace, and at the same quality setting most people cannot tell the difference. Drop your JPG files onto the page, make sure WEBP is selected in the “Convert to” menu — it is the default — and download the results.

WebP is the right output for almost every photo you publish on the web. Browsers have supported it for years, WordPress accepts it, and social platforms handle it.

WebP to JPG, and the Transparency Catch

Sometimes you need to go the other way. A client asks for JPGs, an older tool refuses WebP, or a print shop wants a JPG file. The fix is the same flow in reverse: drop the WebP files in, choose JPG / JPEG in the “Convert to” menu, set the quality, and download.

One thing to remember when you convert WebP to JPG: JPG does not support transparency. If your WebP has a transparent background, the tool fills it with the background colour you choose — white (#ffffff) by default — so check the result before you use it.

Formats: What Goes In, What Comes Out

The tool accepts JPG, PNG, WebP, AVIF, GIF, BMP, TIFF, SVG, ICO, PDF, TGA, QOI and WBMP as inputs. The output list is almost the same, with two exceptions: AVIF is input only, and SVG is input only. You can convert an AVIF file into WebP, JPG or PNG, but you cannot convert other formats into AVIF here.

HEIC is not supported at all. It does not appear in the tool’s supported formats, so a HEIC file cannot be uploaded. If your photo is a HEIC file — the format iPhones use — convert it to JPG or PNG on your own device first, then bring the result here if you need WebP.

AVIF vs WebP: Which One Should You Pick?

AVIF and WebP are both modern formats that make smaller files than JPG. In this tool, the comparison has a simple answer: AVIF is an input format and WebP is an output format. Converting AVIF to WebP is the most useful move, because WebP works everywhere on the web while AVIF support is still catching up. There is no AVIF output here, so the choice is made for you: WebP is the format to convert to.

One detail is worth knowing if you convert AVIF files. Every other conversion happens in your browser, but AVIF is the exception: the page states that all conversions happen in your browser — except AVIF, which our server converts in memory and never stores. So an AVIF file is the one case where your image briefly goes to the server, and it is converted in memory and never stored.

Quality and Size: the Two Settings That Matter Most

The Quality slider runs from 10 to 100 and starts at 80%. The rule is simple: higher quality means a larger file. For photos, 80–90% is usually the best balance, which is why 80% is the default. If the image is a logo, a screenshot or anything with text, try the Lossless option instead — it keeps every detail at the cost of a larger file.

The Resize menu has the sizes people actually need. Leave it on Original Size to keep the image as it is, pick Custom Size to type your own width and height, or use a ready-made preset: Google Discover Recommended 1280 × 720, 1280 × 720 HD / YouTube Thumbnail, 1920 × 1080 Full HD / Video Cover, 1200 × 675 Social Landscape, 1200 × 630 Facebook / Open Graph, 1080 × 1920 Vertical for TikTok / Reels / Shorts / Stories, 1080 × 1350 Instagram Portrait Feed, 1080 × 1080 Square for Instagram / Facebook, and 1200 × 1200 Square High Resolution. The Fit setting decides how the image meets the new size: No Crop / Contain keeps the whole image, Crop Fill / Cover fills the frame, and Stretch Exact Size forces the exact dimensions.

The Four Options, Explained

• Lossless (if supported) — No quality loss, larger file size. Use it for graphics, screenshots and text, where compression artefacts would show.
• Keep EXIF Data — Preserve image metadata. This is on by default, and it keeps details such as camera settings and orientation with the file.
• Auto Rotate — Based on image orientation. This is on by default, and it turns sideways phone photos the right way up.
• Strip Metadata — Remove metadata for smaller size. Use it when you want the smallest file and do not need the metadata.

Keep EXIF and Strip Metadata pull in opposite directions, so pick one: keep the metadata when it matters, and strip it when the smallest file is the goal. Auto Rotate is safe to leave on; it only acts when the photo’s orientation data says the image is sideways.

Privacy: Your Images Never Leave Your Device

The page puts it plainly: “Your images never leave your device.” All conversions happen in your browser, which is why there is no upload step and no sign-up — there is nothing for the site to store, because the files never arrive. The one exception is AVIF, converted in memory on the server and never stored. That is also why the tool asks for nothing: no email, no account, no file history. Close the tab and the images are gone — they were only ever in your browser.

One requirement: the converter runs entirely in your browser, so it needs JavaScript enabled to work. If JavaScript is off, the tool cannot run — enable JavaScript in your browser settings, reload the page, and the converter will appear.

Who Needs It?

Bloggers and site owners preparing images for the web, social media managers resizing the same image for Discover, YouTube, Instagram and Facebook, and anyone who needs a quick JPG-to-WebP or WebP-to-JPG conversion without installing software or handing files to an upload service. If you publish on WordPress, WebP at 80% is the practical default: small files, sharp photos, faster pages.

Checklist: Convert Images Online Without Mistakes

• Check the format: is your file JPG, PNG, WebP, AVIF, GIF, BMP, TIFF, SVG, ICO, PDF, TGA, QOI or WBMP?
• Count your batch: 20 images at a time, no more.
• Pick the output first — WebP for the web, JPG for compatibility, PNG when you need transparency.
• Set quality: 80% is the default, and 80–90% is the best balance for photos.
• Pick a size preset for the platform the image is for — or leave Original Size.
• Decide about metadata: keep EXIF, or strip it for the smallest file.
• Preview the result, check the savings, then download.
