What Is an Image Converter?

An image converter is a tool that changes an image from one file format to another. It decodes the source file into raw pixels, then writes those pixels back out using a different format's rules for compression, color and transparency. That is how a HEIC photo from an iPhone becomes a JPG, or a PNG screenshot becomes a smaller WebP. Every format trades something: JPG is small and opens anywhere but loses fine detail, PNG keeps each pixel and supports transparency but makes bigger files, WebP and AVIF beat JPG on size at the same quality, and HEIC saves space on a phone that few websites accept. The PicsSizer image converter reads 27 formats and writes 20 of them, and every conversion runs inside your browser with no upload.

How the Image Converter Works

  1. 1

    Add Your Files

    Drag your images onto the box or pick them from your device. The converter reads 27 formats, including HEIC, RAW files from Canon, Adobe and Fujifilm, plus PSD, TIFF, SVG and JPEG XL.

  2. 2

    Pick a Format and Settings

    Search the format list and choose your output. Then set quality, turn on resize, pick a background color for transparent areas, or give one file its own output format.

  3. 3

    Convert and Download

    Each row shows the new file size and the percentage saved, with a preview that puts the original and the result side by side. One file downloads on its own and a batch downloads as a single ZIP.

Convert Images Between 27 Input Formats and 20 Output Formats

This converter reads your file, decodes it to raw pixels, and writes those pixels back out in the format you pick. There is no upload step. The decoding runs on ImageMagick compiled to WebAssembly, which works inside your browser on your own device. You get a quality slider from 10 to 100, lossless modes for WebP and AVIF, resizing in the same pass, and metadata stripping that is on by default. Animated GIF and WebP files keep their frames. Each file in a batch can go to a different output format, and everything downloads together as one ZIP.

Which Image Formats Can You Convert?

The converter accepts 27 input formats and writes 20 output formats. Output covers JPG, JPEG, PNG, WebP, AVIF, GIF, TIFF, BMP, PSD, PSB, JXL, EPS, EXR, HDR, TGA, WBMP, PNM, PPM and SGI. SVG is in the output list too, but it wraps the pixels rather than tracing them into vector paths. PDF is not handled here, so use the PDF to Image tool for that. Input covers these groups:

  • Photos and web images: JPG, JPEG, PNG, WebP, AVIF, GIF, BMP
  • Phone and camera files: HEIC, HEIF, CR3 from Canon, DNG from Adobe, RAF from Fujifilm
  • Design and print files: PSD, PSB, TIFF, SGI
  • High dynamic range and scientific: HDR, EXR, PFM, JP2, J2K, J2C
  • Newer formats: JXL (JPEG XL), AVIF, APNG
  • Vector input: SVG, which is rasterized to pixels on the way in

Give Each File Its Own Output Format

Every row in the file list has its own format dropdown. Set the main output format once in the settings panel, then change any single row to something else and it gets marked as an override. A mixed folder can leave as PNG for the flat graphics and JPG for the photos in one run, so you never have to split the batch or convert twice.

Quality Slider and Lossless Modes

The quality slider runs from 10 to 100 and starts at 90. It only appears for JPG, JPEG, WebP, AVIF and JXL, because those are the formats where it changes the picture. For PNG, GIF, TIFF, BMP and the rest, the panel says the slider does not apply instead of showing a control that does nothing. WebP and AVIF have a Lossless toggle that keeps every pixel exact and switches the slider off. JPG and JPEG have a Progressive toggle, which makes a large photo appear in rough form first and sharpen as the rest arrives.

Keep Animation When You Convert a GIF

Animated files keep every frame when the output format is GIF or WebP. Those two are the only output formats here that store more than one frame, so any other choice flattens the file to a single still. The editor tells you before you convert: a green note when every animated file will keep its frames, and an amber warning naming how many will lose them. Animated PNG is the one exception. It cannot be read frame by frame in this build, so no output format will carry its animation across.

Resize While You Convert

Open the Resize section, turn it on, and type a width, a height, or both. The lock button keeps the aspect ratio and is on by default, so filling in one side scales the other to match. Unlock it and four fit modes appear. Fit keeps the ratio with no padding, Contain pads out to the exact box in a color you choose, Cover fills the box and crops the overflow, and Stretch forces the exact numbers. Resizing runs in the same pass as the conversion, including on every frame of an animation.

Save a Transparent PNG as JPG Without a Black Box

JPG, BMP and the other formats with no alpha channel cannot store transparency. Pick one of them and a Transparent background panel appears with a color picker and a hex field. White is the default, and every transparent pixel fills with the color you set. PNG, WebP, AVIF, GIF and TIFF keep the alpha channel exactly as it was, so nothing gets filled in.

Strip EXIF, IPTC and GPS Data

Strip metadata sits in the Privacy section and is on by default. It removes the GPS coordinates, camera make and model, and capture time that phones write into every photo. It also drops IPTC fields and the embedded color profile, which trims a little off the file size. Switch it off when a client needs the shooting details, or when a print job depends on the color profile staying with the file.

Convert a Batch and Download One ZIP

Add as many files as you like. Each row shows the original size and pixel dimensions, then the new size with the percentage saved once it finishes. Rows get their own progress bar, a status badge, and a retry button when one fails. A single file downloads on its own. Two or more arrive as picssizer_converted.zip, with colliding names numbered so a photo.png and a photo.webp converted to JPG never overwrite each other. If a file could not be converted, a message tells you how many were left out of the archive.

What Is the Best Format to Convert To?

It depends on where the image is going. Use this as a starting point:

  • Photos on a website: WebP at quality 80 to 85, with JPG as the fallback for older software
  • Smallest possible photo: AVIF, which usually beats WebP by another 20% to 30%
  • Logos, icons and screenshots: PNG, or WebP with Lossless turned on
  • Files that must open anywhere: JPG
  • Animation: WebP for a smaller file, GIF when the destination only takes GIF
  • Print or archive masters: TIFF, which keeps every pixel
  • More editing in Photoshop later: PSD

Why Convert Images in Your Browser

Your files stay on your device, which matters for client work, unreleased product shots, and anything covered by an NDA. There is no upload wait and no queue, so a small file converts as fast as your laptop can decode it. Nothing sits behind an account either: no daily cap, no file count limit, and no watermark on the output. The limits come from your own hardware instead of a server, so very large files depend on how much memory your device has, and any file that stalls is cut off after 120 seconds to keep the rest of the batch moving.

Who Uses the Image Converter

Web developers converting PNG exports to WebP or AVIF to cut page weight. iPhone owners turning HEIC photos into JPG so they open on Windows. Photographers exporting CR3, DNG and RAF files to shareable JPG previews. Designers flattening PSD and TIFF masters for the web. Marketers turning a heavy animated GIF into a much smaller animated WebP. Anyone who needs GPS and camera data gone from a photo before it gets shared.
