What is an image converter?
An image converter changes a file from one format to another — for example JPG to WebP or SVG to PNG — so assets work for websites, print, email, or sharing. This Web6 tool performs conversion entirely in your browser.

Supported conversion matrix
| Input | Typical outputs |
|---|---|
| JPG / JPEG | PNG, WebP, AVIF, PDF, SVG container |
| PNG | JPG, WebP, AVIF, PDF, SVG container |
| WebP | JPG, PNG, AVIF, PDF, SVG container |
| AVIF | JPG, PNG, WebP, PDF, SVG container |
| SVG | PNG, JPG, WebP, AVIF, PDF, sanitized SVG |
| JPG, PNG, WebP, AVIF (rasterized pages) |
Raster-to-raster conversion may involve recompression. SVG-to-raster needs output dimensions. PDF-to-image rasterizes pages. Raster-to-SVG container is not vectorization.
Image conversion guide
How to convert image formats
Upload files, choose an output format or preset, adjust quality/resize/transparency if needed, preview, convert in the browser, then download individually or as a ZIP.
JPG vs PNG
JPG suits photographs and generally smaller photo files, but it does not support transparency and uses lossy compression. PNG is lossless and supports transparency, which often means larger photo files but sharper graphics and logos.
WebP vs JPG
WebP often delivers smaller files than JPG at comparable quality for web delivery. Availability depends on browser encode support, which this tool detects before offering WebP output.
AVIF vs WebP
AVIF can compress further than WebP for many photos, with slower encode times and uneven browser support. If AVIF encoding is unavailable, the tool disables AVIF output instead of mislabeling another format.
When to use PNG
Prefer PNG for logos, UI graphics, screenshots with text, and any asset that needs a transparent background.
When to use JPG
Prefer JPG for photographs, social media uploads that expect JPEG, and email attachments when transparency is not required.
When to use WebP
Prefer WebP for modern websites and Shopify product images when you want smaller files with good quality and optional transparency.
When to use AVIF
Prefer AVIF for next-generation website delivery when your audience browsers can decode it and your tooling can encode it locally.
How transparency works
PNG, WebP, AVIF (encoder permitting), and SVG can keep transparent pixels. JPG cannot. Converting transparent images to JPG fills transparent areas with a background color.
Why file size may increase after conversion
Lossless targets, higher quality, larger dimensions, or already-optimized inputs can produce larger outputs. Conversion is about format fitness, not guaranteed shrinkage.
Does converting JPG to PNG improve quality?
No. Quality already discarded by JPEG compression cannot be recovered by wrapping the pixels in a PNG file.
How to convert SVG to PNG
Upload an SVG. The tool sanitizes scripts and unsafe references, rasterizes at your scale or dimensions, then encodes PNG. Provide dimensions if the SVG has no size or viewBox.
Why raster images cannot become true vectors automatically
Automatic tracing is excluded from version 1. Raster-to-SVG only embeds the bitmap inside an SVG container and is clearly labeled as such.
How to convert images to PDF
Choose PDF as the output for each image, or Combine to PDF for one multi-page document. Page size, margins, and fit options control layout. Generation uses jsPDF in the browser.
How to convert PDF pages to images
Upload a PDF, set page range and scale, choose JPG/PNG/WebP/AVIF, and convert. Pages are rasterized with PDF.js locally. Encrypted PDFs are not supported.
How browser-based conversion protects privacy
Files stay in memory as object URLs. Preferences may use localStorage/sessionStorage, but image binaries are never stored there and are never sent to Web6 or third-party conversion APIs.
Best image formats for websites
Use WebP or AVIF for photos when supported, PNG for transparent graphics, and JPG as a widely compatible fallback. Strip unnecessary metadata and avoid upscaling.
Best image formats for Shopify product images
WebP or high-quality JPG usually works well for product photos. Keep dimensions sensible for theme breakpoints and remove EXIF when privacy or size matters.
Common image conversion mistakes
Expecting JPG→PNG to restore detail, treating SVG containers as vectors, ignoring transparency loss to JPG, converting huge PDFs without page limits, and assuming every conversion shrinks the file.
FAQ
Image converter FAQs
Answers about formats, privacy, SVG, PDF, batch conversion, transparency, and browser support.
Is the Web6 Image Converter free?
Yes. The tool is free, requires no account, and converts files only on your device.
Are my files uploaded to Web6?
No. Your files are converted directly in this browser. Web6 does not upload, store, or view your images or documents.
Which image formats are supported?
Inputs: JPG, JPEG, PNG, WebP, AVIF, SVG, PDF, plus optional GIF (first frame) and BMP. Outputs: JPG, PNG, WebP, AVIF (when the browser can encode it), PDF, sanitized SVG, and SVG container with an embedded raster image.
Can I convert JPG to PNG?
Yes. Upload a JPG, choose PNG, convert, and download. Note that JPG-to-PNG does not restore quality already lost in the JPEG.
Can I convert PNG to JPG?
Yes. Choose JPG as the output. Transparent areas are filled with your selected background color because JPG does not support transparency.
Can I convert JPG to WebP?
Yes when your browser supports WebP encoding. Most modern browsers do.
Can I convert WebP to JPG?
Yes. Decode WebP in the browser, then encode as JPG with your quality setting.
Can I convert PNG to AVIF?
Yes when the browser supports AVIF encoding. If AVIF is unavailable, the option is disabled — the tool will not write a fake AVIF file.
Can I convert AVIF to PNG?
Yes when the browser can decode AVIF. Then export as PNG or another available format.
Can I convert SVG to PNG?
Yes. SVG is sanitized first, then rasterized at your chosen scale or dimensions and encoded as PNG.
Can I convert SVG to JPG?
Yes. After sanitization and rasterization, the image is encoded as JPG with a solid background.
Can I convert an image to PDF?
Yes. Choose PDF output for one image per file, or use Combine to PDF for multiple images in one document.
Can I convert PDF pages to JPG?
Yes. Pages are rendered locally with PDF.js and exported as JPG. Password-protected PDFs are rejected.
Can I convert PDF pages to PNG?
Yes. Select PNG as the output format and optionally set a page range.
Can I convert multiple images at once?
Yes. Upload up to 100 files (50 MB each, 500 MB total), then convert the batch.
Can I download converted files as ZIP?
Yes. Use Download all as ZIP. ZIP entries are created in the browser with safe path names.
Does JPG support transparency?
No. JPG fills transparent pixels with a background color you choose (default white).
What happens to transparency when converting PNG to JPG?
Transparent areas are flattened onto the selected background color. A warning is shown when JPG output is selected.
Does converting JPG to PNG improve quality?
No. Converting JPG to PNG does not restore lost image quality. It only changes the container format.
Is WebP better than JPG?
Often WebP can be smaller at similar visual quality for photos, but results vary by image and encoder. Presets are starting points, not universal rules.
Is AVIF better than WebP?
AVIF can be more efficient for many photos when encoding is supported, but encoding is slower and browser support varies.
Can I resize an image during conversion?
Yes. Resize by width, height, percent, longest/shortest edge, max box, or exact dimensions, with aspect-ratio and never-upscale options.
Can I remove metadata?
Yes. Metadata removal is the default. Canvas re-encoding typically strips EXIF, GPS, and similar fields.
Are animated GIFs supported?
Version 1 converts only the first frame of animated GIF files. Animation is not preserved.
Can the tool convert HEIC?
Not in version 1. HEIC/HEIF files are rejected unless a reliable local decoder is added later.
Does SVG output create editable vector paths?
No. Raster-to-SVG creates an SVG container with an embedded raster image. That is not true vectorization. Sanitized SVG export is only for SVG inputs.
Why is the converted file larger?
Re-encoding, lossless formats, higher quality, or larger dimensions can increase size. Size change is reported as smaller, larger, or similar.
Can I use the tool on mobile?
Yes. The layout uses stacked tabs on small screens for Files, Convert, Preview, and Results.
What is the maximum file size?
Each file may be up to 50 MB. Batches are limited to 100 files and about 500 MB total input.
Does the tool work offline?
After the page and any needed libraries (such as PDF.js) have loaded, conversion runs locally without uploading files. A network connection is not required to process files already on the page.
