TL;DR: Upload an image and choose a target format (JPG/PNG/WebP/AVIF/TIFF/BMP/GIF) to convert it in your browser.
Convert images online for free — change between WebP, PNG, JPG, TIFF, BMP and HEIC formats instantly. Perfect for converting iPhone HEIC photos to JPG. No upload required.
Image Format Converter is part of PrivaTools — a free, open-source alternative to iLovePDF, Smallpdf, and Adobe. Server-side tools process your file in an isolated container and discard it immediately; many tools never upload at all and run entirely in your browser.
PNG for graphics with transparency or crisp text/UI elements. JPG for photos (smaller files at near-identical quality). WebP for web delivery (smaller than JPG at the same quality, supported by all modern browsers). TIFF for archival or print workflows. HEIC for iPhone-style storage (limited compatibility outside Apple). AVIF for cutting-edge web (smallest of all, but newer browsers only).
EXIF is stripped during conversion by default for privacy (GPS, camera model, timestamps removed). Use View EXIF first to record any metadata you want to keep, or use the 'preserve metadata' toggle in advanced options if your destination workflow needs the original EXIF.
Yes — upload multiple images and all are converted to the chosen format, then bundled into a ZIP. For format-specific batch workflows you can also use the dedicated tools (jpg-to-png, heic-to-jpg, webp-to-png, etc.) which preselect the input/output formats.
Yes. The images are held in temp memory inside an isolated Docker container for the conversion pass only — both input and output are unlinked the moment your download begins. Nothing is logged, no thumbnail is kept, no copy is sent to any third-party API. The conversion uses libvips/Pillow locally.
500 MB per file with no daily or monthly quota. Maximum image dimensions are 100 megapixels (about 10000x10000 pixels) — sufficient for full-resolution DSLR RAW conversions.
Format-to-format quality depends on the codec. PNG → PNG, PNG → TIFF: lossless. JPG → PNG, HEIC → PNG: lossless (no re-encoding). JPG → JPG at quality 90+: imperceptibly lossy. JPG → WebP at quality 80: typically indistinguishable. Avoid stacked lossy conversions (JPG → JPG → JPG) which compound artifacts.
No — no account, no email, no sign-up. Upload, convert, download. Privacy guarantees are architectural.
Free with no daily limit (Convertio caps free use to 100 MB/day), no account required, no watermark on the output, and we support more formats than the freemium converters (HEIC, AVIF, JPEG XL in addition to the standard set). The conversion pipeline is open source and self-hostable.
