Supported Formats Explained

PDF (Portable Document Format)

JPG/JPEG (Joint Photographic Experts Group)

Best for photos. Lossy compression, small file size, universal compatibility. Ideal for web and sharing.

PNG (Portable Network Graphics)

Lossless compression, supports transparency. Ideal for graphics, logos, screenshots, and images requiring perfect quality.

WEBP (Google Image Format)

Modern format by Google. Superior compression to JPG/PNG with smaller file sizes while maintaining quality. Growing browser support.

HEIC (High-Efficiency Image Container)

Apple's default photo format since iOS 11. High efficiency but limited compatibility outside Apple ecosystem. Often needs conversion to JPG.

AVIF (AV1 Image File Format)

Next-gen format with even better compression than WEBP. Smaller file sizes with excellent quality. Newer but growing browser support.

SVG (Scalable Vector Graphics)

Infinite resolution, perfect for logos and icons. Can be converted to raster formats (PNG/JPG) for universal use.

BMP (Bitmap)

Legacy bitmap format. Uncompressed, large file sizes. Rarely used today but still supported for compatibility.

GIF (Graphics Interchange Format)

Supports animation. Limited to 256 colors. Best for simple animations and retro aesthetics. Note: For advanced GIF creation with timeline control, use our dedicated GIF Maker.

ICO (Icon Format)

Windows icon format. Used for website favicons and application icons. Extract high-quality graphics from icon files.

Base64 (Data Encoding)

Text representation of binary data. Used for embedding images directly in code (CSS, HTML, JSON). Eliminates HTTP requests for small assets.

Pro Tips For File Conversion

When to use JPG vs PNG

JPG for photos (smaller size, lossy), PNG for graphics with transparency (lossless, larger size).

WEBP vs AVIF

WEBP has broader browser support (95%+), AVIF offers better compression (30% smaller) but newer browsers only (85%+). Use WEBP for maximum compatibility.

HEIC to JPG Strategy

Always convert HEIC to JPG when sharing with Windows users or uploading to older web forms to ensure maximum compatibility without losing visual detail.

Batch processing best practices

Use ZIP download for organization. Files keep original names. Process in batches of 20-30 files for optimal performance on mobile devices.

Quality settings guide

For web use, 80-85% quality is often indistinguishable from 100% but results in 50% smaller files. For print, use 95-100%.

Metadata privacy

EXIF data contains camera settings, GPS location, date/time. Remove metadata before sharing sensitive photos online using our "Remove EXIF" option.

Frequently Asked Questions

Is there a file size limit?
No hard limits imposed by us. It depends on your device's memory and browser capacity. We've tested with 50MB+ files smoothly on desktop. For mobile devices, we recommend up to 20MB for best performance.
Can I convert multiple files at once?
Yes, use batch mode to convert dozens of files simultaneously. You can download as individual files or receive everything packaged in a single ZIP archive for easy organization.
Will I lose quality during conversion?
It depends on the formats. Converting from lossless (PNG) to lossy (JPG) will reduce quality slightly. Use our quality slider (1-100%) to control the balance between file size and visual quality. Converting between same-type formats (JPG to PNG) preserves 100% quality.
Can I convert PDF to editable Word documents?
No, we focus on image and format conversion. PDF to Word requires OCR (Optical Character Recognition) technology which is beyond our current scope. We can extract PDF pages as images though.
Are my files uploaded to your servers?
Absolutely not. All processing happens 100% locally in your browser using your device's power. Your files never leave your device, never travel across the internet, and are completely private.
Can I convert videos or audio files?
Currently we focus on images, documents, and code formats (PDF, JPG, PNG, WEBP, HEIC, AVIF, SVG, Base64, etc.). Video and audio conversion is not supported at this time.
Is it really free? Are there hidden limits?
Yes, 100% free forever. No hidden fees, no subscriptions, no daily limits, no watermarks. All features available to all users without registration or payment.
Is it safe to convert sensitive documents (like IDs or contracts) to PDF or JPG online?
Yes, it is 100% safe. Unlike cloud converters, our tool processes files strictly locally in your browser. Your sensitive documents never travel over the internet or touch our servers.
How do I convert HEIC files to JPG on a Windows PC?
Simply drag and drop your iPhone HEIC photos into our converter, select JPG as the output format, and click convert. The tool handles the Apple-specific format natively in your browser.
