Konverzia WEBP na JPG

What WEBP na JPG does

Converting an image changes its file format while keeping the picture. You need it when a website, app or printer does not accept a format, for example an iPhone HEIC photo, a WEBP image saved from a browser, or a PNG that should become a smaller AVIF.

The tool decodes the file into plain pixels with your browser's image decoder, then encodes those pixels again in the new format. HEIC photos the browser cannot open use a built-in HEIC decoder. Only the pixels are carried over: the width and height stay the same (except for ICO, which is scaled to the icon size), and metadata is not copied.

When to use WEBP na JPG

• Turn iPhone HEIC photos into JPG so they open in Windows apps, online forms and older photo viewers.
• Save WEBP images downloaded from a website as PNG or JPG so they can be edited in any program.
• Convert large PNG screenshots or product photos to WEBP or AVIF so web pages load faster.
• Make a website icon by converting a square logo into an ICO file between 16 and 256 pixels.

Settings explained

Output format

Chooses the format to save. JPG suits photos, PNG keeps sharp edges and transparency, WEBP and AVIF give smaller files, BMP is uncompressed and ICO is for icons. Shown only when the tool offers several formats.

Quality

Shown for JPG, WEBP and AVIF output. It ranges from 10 to 100 and starts at 90. Values between 75 and 90 give small files that look the same as the original on screen.

Background color

JPG and BMP cannot store transparency, so transparent pixels are filled with this color. The default is white. Pick a color that matches the page or document where the image will be placed.

Icon size

Shown when saving as ICO. The image is scaled to fit inside a square of 16 to 256 pixels and centered, with transparent space around it if it is not square. Use 32 or 48 for website icons.

SVG render width

Shown when SVG files are accepted. Sets the width in pixels used to draw a vector file before it is converted; the height follows the aspect ratio. Leave 0 to use the size defined in the file.

What changes when you convert WEBP to JPG

JPG does not support transparency. Transparent areas in your WEBP file are filled with a solid background color, white by default.

JPG cannot store animation. If your WEBP file is animated, only the first frame is converted.

Format comparison

Čo je WEBP?

WEBP (WebP) je obrazový formát z roku 2010, ktorého autorom je Google. Formát podporuje stratovú aj bezstratovú kompresiu, podporuje priehľadnosť a dokáže uložiť animáciu. Súbory majú príponu .webp.

WebP was developed by Google to make images on the web smaller. Its lossy mode is based on the VP8 video codec, and it also has a separate lossless mode. Both modes can include an alpha channel for transparency. The format also supports animation, so it can replace JPG, PNG and GIF in many cases.

WebP is a good choice for images on websites and in apps, where smaller files load faster. It works for photos, graphics with transparency and short animations, often at a smaller size than JPG, PNG or GIF.

Some older software, image editors, print services and upload forms still do not accept WebP. Lossy WebP always reduces color resolution, which can blur fine colored detail. At very high quality settings, the size benefit over JPG can be small.

All current major browsers display WebP, including Chrome, Edge, Firefox and Safari on recent versions of macOS and iOS. Windows, macOS, Android and most modern image editors open it, but some older desktop programs do not.

Čo je JPG?

JPG (Joint Photographic Experts Group) je obrazový formát z roku 1992, ktorého autorom je JPEG. Formát používa stratovú kompresiu a nepodporuje priehľadnosť. Súbory majú príponu .jpg alebo .jpeg.

JPG, also written JPEG, is named after the Joint Photographic Experts Group, which wrote the standard. It splits an image into small blocks, transforms each block with a discrete cosine transform and discards the fine detail that the eye notices least. A quality setting controls how much detail is removed and therefore the file size.

JPG is the standard choice for photographs and other images with smooth color gradients, such as camera pictures, product photos and images for email or social media. It gives small files with good visual quality at moderate settings.

JPG does not support transparency or animation. Each time a JPG is edited and saved again, it loses a little more quality. Text, line art and sharp edges can show visible blocks or halos at low quality settings.

JPG is supported everywhere: in all web browsers, on all desktop and mobile operating systems, and on cameras, phones and printers. All image editors and office programs open it. It is the most compatible format for sharing photos.

Prečo používať nástroj WEBP na JPG od FansBond

Väčšina online konvertorov nahráva vaše súbory na svoje servery. Nástroj „WEBP na JPG“ od FansBond namiesto toho pracuje priamo vo vašom prehliadači vďaka WebAssembly a moderným rozhraniam prehliadača. Súbory zostávajú vo vašom zariadení, čo je bezpečnejšie pre súkromné fotky, zmluvy aj nezverejnenú prácu, a často je to aj rýchlejšie, pretože sa nič nemusí nahrávať ani sťahovať.

Žiadne fronty, žiadne vodoznaky a žiadny účet. Keď sa stránka načíta, nástroj funguje aj na pomalom pripojení.

Tips for the best result

• Animated GIF and WEBP files are converted from their first frame only. Use the GIF tools if you need to keep the animation.
• Use PNG for screenshots, logos and images with text. Lossy formats can blur sharp edges and add faint marks around letters.
• An ICO file made here contains one size. If you need several icon sizes, convert the same logo again with a different icon size.
• Converting a JPG to PNG does not bring back detail lost to JPG compression; it only prevents further loss when you edit and save again.

How WEBP na JPG works in your browser

When you add an image, the browser decodes it into raw pixels on your device. HEIC photos are decoded with a browser build of libheif, and AVIF with the libavif decoder. The pixels are then processed on an HTML canvas and encoded again in the format you picked.

JPG, PNG and WebP are encoded with your browser's built-in encoders, and AVIF with libavif compiled to WebAssembly. The compressors add MozJPEG for smaller JPG files and OxiPNG for lossless PNG optimization. Because everything runs locally, the speed depends on your device rather than on a server queue.

Privacy and security

Most online converters upload your files to a server, process them there and keep a copy for some time. WEBP na JPG works differently: the code is downloaded to your browser once, and your files are read and written only on your device.

You can check this yourself: after the page has loaded, turn off your internet connection and the tool still works. This makes it safe for contracts, IDs, medical records, private photos and unreleased work.
