Split Image creates equal image pieces and downloads them as a ZIP. Use rows only for horizontal strips, columns only for vertical strips, or both rows and columns for a full grid.
Drag the crop box over the image, then resize it from the corners or edges. The numeric values update automatically for precise output.

Prismix Image Converter is built around a reliable Sharp-powered image engine. Core browser and web publishing formats such as JPG, JPEG, PNG, WebP, GIF, AVIF, TIFF and SVG are the strongest baseline. HEIC and HEIF input is handled with a stronger production flow: Prismix uses a portable libheif-based decoder first, then a second fallback decoder, then native server decoding when available. Output to HEIC or HEIF is attempted through the server encoder when available, while JPG, PNG, WebP, AVIF, GIF, TIFF, SVG, ICO and image-to-PDF remain the fastest baseline choices for broad web use.
High-intent image conversion shortcuts
Fast image conversion

Convert, compress, resize and crop images in three clear steps
Upload your image
Choose one image or drop a batch of up to 10 files. Prismix shows colorful thumbnail previews so users can confirm the right files before processing.
Select the output
Pick JPG, PNG, WebP, AVIF, GIF, TIFF, SVG, ICO or PDF. Then tune quality, target size, resize dimensions or crop coordinates depending on the selected mode.
Download instantly
After conversion, the result card shows old file size, new file size, quality savings and a responsive download button that does not overflow on mobile.
Free image converter for web creators
Use Prismix Image Converter when you need to turn PNG screenshots into JPG, export JPG photography as WebP, create AVIF files for modern websites or package images as PDF. The interface is designed for speed, readable controls and a workflow that works well for daily website, marketplace, school and social media tasks.
Compress images without confusing settings
Large image files slow pages, waste storage and make uploads harder. Compress mode lets users choose a quality value and a target size in KB. This gives a practical path for common searches such as compress image to 1 MB, reduce JPG size, optimize PNG or make a WebP file smaller.
Resize images for websites and social media
Resize mode supports width, height and fit behavior. Users can keep images inside a box, cover an area, contain with background or stretch when they intentionally need exact dimensions. This is useful for banners, product photos, avatars, thumbnails and mobile content.
Crop preview for safer editing
Crop mode provides a preview area and numeric controls so users can adjust the crop before downloading. This prevents blind processing and gives a more professional editing experience for profile photos, listing images and article visuals.
Image to PDF conversion
Prismix can export images to PDF for document sharing, invoices, homework, reports and archive workflows. The image-to-PDF option gives users a quick way to package visual files without needing a separate desktop app.
AdSense-ready but user-first
The layout includes clearly separated advertisement areas while keeping upload, conversion and download buttons free from misleading ad placement. The core tool stays easy to use, because strong user experience is also important for long-term organic growth.
Which image format should you choose?
| Format | Best for | Strength | Common search intent |
|---|---|---|---|
| JPG / JPEG | Photos and small sharing files | Wide compatibility | PNG to JPG, compress JPG |
| PNG | Transparent graphics and screenshots | Lossless quality | WebP to PNG, resize PNG |
| WebP | Modern web pages | Great size-to-quality balance | JPG to WebP, PNG to WebP |
| AVIF | Very small modern images | Advanced compression | AVIF converter, AVIF to JPG |
| SVG | Logos and vector graphics | Scalable graphics | SVG converter |
| Documents and sharing | Easy document packaging | Image to PDF |
Why image conversion and compression matters
Images are often the heaviest assets on a page. A single unoptimized product photo, blog hero image or social media export can be several megabytes larger than necessary. Prismix Image Converter helps users choose a better format, reduce file size, resize dimensions and export files in a format that matches the final use case.
For websites, WebP and AVIF can reduce image weight compared with traditional formats when browser support is acceptable. For transparent graphics, PNG can still be the right choice. For universal photo sharing, JPG remains practical. For documents, image-to-PDF is often the simplest output. This page is intentionally structured with clear headings, direct answers and internal links so both users and crawlers can understand every tool area.
Prismix also targets high-intent conversion workflows such as HEIC to JPG, HEIF to JPG, JPG to WebP, PNG to JPG, WebP to PNG, AVIF to JPG, compress image to 1 MB, resize image online and crop image with preview. These sections are intentionally written in plain language so search engines can match the page to real user intent while visitors still get a clean tool-first experience.
The platform avoids fake promises and is designed for production trust. Common web formats are handled directly by the image engine. HEIC and HEIF input uses portable fallback decoders for common iPhone photos, and HEIC/HEIF output is attempted when the deployment server includes the required encoder support. If an environment cannot encode a requested advanced format, Prismix returns a precise message instead of delivering a broken file.

Frequently asked questions
Can I convert PNG to JPG?
Yes. Upload your PNG file, choose JPG as the output format and click Convert Now.
Can I convert JPG to WebP?
Yes. WebP is a strong modern web format and is available in the output format selector.
Can I convert images to PDF?
Yes. Select PDF as the output format to create a PDF document from your uploaded image or images.
Can I compress a 20 MB image close to 1 MB?
Use Compress mode and set a target size such as 1024 KB. Very detailed images may need lower quality or smaller dimensions to reach the target.
Can I resize images to exact dimensions?
Yes. Enter width and height values, then choose a fit mode such as inside, cover, contain, fill or outside.
Does crop mode show a preview?
Yes. Crop mode includes an interactive preview. Users can drag the crop area directly on the photo, resize it from the handles and fine-tune values numerically.
How does HEIC and HEIF conversion work?
Prismix first uses a portable libheif-based HEIC/HEIF decoder, then a second HEIC fallback decoder, and finally native Sharp/libvips if the server has the right plugins. HEIC/HEIF output is attempted when the server has HEIF/HEVC encoder support.
Do you store my images?
No. Files are processed in memory for the current request and browser previews are cleared when the page reloads.
Is there a file limit?
Yes. The interface limits batch uploads to 10 files to keep the tool stable and fast.
Is Prismix Image Converter mobile-friendly?
Yes. The upload area, controls, result cards and download button are responsive for mobile screens.
Can I use this for e-commerce images?
Yes. Resize and compression tools are useful for marketplace product photos, store images and catalog visuals.
What output should I choose for website speed?
WebP is a practical default for many websites. AVIF can be smaller, while JPG remains useful for broad compatibility.
