How to convert an image
Why convert an image?
Image formats are not interchangeable, and the wrong one causes friction everywhere. A content platform rejects your upload because it expects JPEG, not HEIC. A website audit tells you to serve WebP or AVIF to pass its performance checks. A print shop insists on TIFF for a poster. A favicon generator only takes ICO. A photo exported from an iPhone arrives as HEIF that your editor can't open. Converting is how you move a picture from the format you have to the format a tool actually accepts.
Under the hood, converting is more than a rename. Each format stores pixels differently: JPEG throws away detail the eye barely notices to shrink photos, PNG keeps every pixel exactly and adds transparency, WebP and AVIF use newer compression to beat both on size, and TIFF and BMP prioritize fidelity for archival and interchange. This converter decodes your file into a clean RGBA buffer, applies the correct orientation, then re-encodes it into the target format with high-quality defaults — all over an encrypted connection, with the uploaded bytes discarded the instant the result is sent back.
Image formats at a glance
A quick comparison of the formats this tool handles, so you can pick the right target:
| Format | Compression | Transparency | Best For |
|---|---|---|---|
| JPEG | Lossy | No | Photographs, most camera images |
| PNG | Lossless | Yes | Logos, screenshots, sharp-edged graphics |
| WebP | Both | Yes | Modern web images, smaller than JPEG/PNG |
| AVIF | Both | Yes | Newest web codec, smallest files |
| GIF | Lossless | 1-bit | Simple animations, low-color graphics |
| TIFF | Lossless | Yes | Print, scanning, archival masters |
| BMP | None | Optional | Raw uncompressed interchange |
| ICO | Mixed | Yes | Favicons and app icons |
When to convert which format
• PNG or HEIC to JPEG — when a photo needs to be smaller or a tool refuses anything but JPEG. Expect a large size drop with little visible loss.
• JPEG to WebP or AVIF — the highest-impact web optimization. The same photo often lands 25–50% smaller with no perceptible difference, which improves page-load scores.
• Anything to PNG — when you need transparency or a pixel-perfect copy of a screenshot, diagram, or logo with crisp edges.
• Photo to TIFF — when a printer or archive asks for an uncompressed, high-fidelity master.
• PNG or JPEG to ICO — when you're building a favicon or a desktop app icon.
Transparency and quality, explained
Two details trip people up. The first is transparency: PNG, WebP, AVIF and GIF can store an alpha channel, but JPEG cannot. Convert a transparent PNG to JPEG and the see-through areas are flattened onto a solid background — usually white. If you need the transparency, target PNG or WebP instead. The second is quality: converting to a lossless format (PNG, TIFF) never degrades the image, but converting to a lossy one (JPEG, WebP, AVIF) re-encodes the pixels. This tool uses high-quality encoding settings so a single conversion is visually clean; the thing to avoid is repeatedly re-saving the same photo as JPEG, because each pass compounds the loss.

Image formats explained →Frequently asked
Is the image converter free?
Yes — no signup, no watermark, and no daily quota. Every conversion is free.
Which image formats are supported?
JPEG, PNG, WebP, GIF, TIFF, BMP, ICO and AVIF — each works as both input and output.
What's the difference between JPG and PNG?
JPEG is lossy and ideal for photographs, giving small files at slight quality cost. PNG is lossless with transparency, ideal for logos, screenshots and graphics with sharp edges.
Should I use WebP or AVIF for the web?
Both beat JPEG and PNG on size. AVIF usually compresses smaller at the same quality, while WebP has slightly wider support in older software. For most sites in 2025, either is a strong choice.
What's the max file size?
10 Mb per image. For very large photos, resize them first, then convert.
Will transparency be preserved?
Yes, when both formats support an alpha channel (PNG, WebP, AVIF, GIF). Converting a transparent PNG to JPEG flattens transparency onto a solid background, since JPEG has no alpha channel.
Does converting lose quality?
Converting to a lossless format (PNG, TIFF) is quality-preserving. Converting to a lossy format (JPEG, WebP, AVIF) re-encodes the pixels; we use high-quality defaults so the loss is visually minimal.
Are my files stored?
No — files travel over an encrypted connection, are processed in memory, and are auto-deleted right after conversion.
