Frequently Asked Questions

What is the best image format for websites?

WebP is the best format for websites in 2025. It produces 25–35% smaller files than JPEG with similar quality, and supports transparency. It is supported by 97%+ of browsers.

Does converting from JPEG to PNG improve quality?

No. Converting from a lossy format (JPEG) to a lossless one (PNG) does not recover quality that was already lost. The PNG will be larger but not sharper than the JPEG.

Will EXIF metadata be preserved?

EXIF metadata (camera settings, GPS location, date) is preserved by default. You can optionally strip all metadata for privacy before downloading.

What is AVIF format?

AVIF (AV1 Image File Format) is the newest image format, producing files 30–50% smaller than WebP. It is supported by modern Chrome, Firefox, and Safari.

About Image Converter

Design sent you a folder of logo PNGs and the ad network's spec sheet demands JPEG. Or a client shipped you a stack of BMP files from a Windows-only scanner and your CMS refuses to ingest anything but WebP. This converter handles JPEG, PNG, WebP, BMP, and GIF in both directions, using the appropriate encoder for each target — mozjpeg for JPEG output, oxipng for PNG, libwebp for WebP, and native canvas encoders for BMP and single-frame GIF. It surfaces the trade-offs each format forces: converting a PNG with transparency to JPEG will flatten onto a solid background (pick the color here rather than getting a surprise white), converting JPEG to PNG locks in the existing JPEG artifacts as lossless pixel data (making the file bigger with no quality gain), and converting a GIF animation into JPEG keeps only the first frame. Batch mode accepts up to 20 files at once and applies the same target format across the whole set, with a preview of each output next to its source before you download as a ZIP.

When to use this tool

Converting transparent PNG logos to ad-network JPEGs

Google Display Network and most ad servers reject PNG with alpha and require JPEG. Set the background color to match the intended ad slot (white for search ads, the brand accent for display), convert to JPEG quality 92, and your logo renders correctly in every ad unit instead of showing black where transparency used to be.

Normalizing a folder of mixed-format product photos

Vendor uploads come in as a chaotic mix of BMP, TIFF-exported-as-PNG, and variable-quality JPEG. Batch-convert all to WebP at a single quality setting and you get a uniform library that compresses well, renders consistently, and fits within most e-commerce image-pipeline assumptions.

Getting an old BMP screenshot into a modern CMS

Some legacy Windows applications (SAP GUI, older barcode scanners) still export BMP, which most content platforms reject. Drop the BMP in, pick PNG as output, and you get a web-safe lossless version that uploads to WordPress, Ghost, Contentful, or Notion without format-gate errors.

Preparing images for a print brochure

Print shops typically want CMYK TIFF or at least high-quality JPEG, not WebP (which most print RIPs still do not handle). Convert the design team's WebP exports back to JPEG at quality 95 with minimal subsampling, and the file goes through the print workflow without the RIP throwing a format error at layout time.

Creating a static thumbnail from an animated GIF

You want a single-frame poster image to lazy-load before a video or GIF plays. Convert the source GIF to JPEG or PNG and we extract frame zero only, giving you a lightweight thumbnail to show as a placeholder until the full animation loads on hover or scroll.

How it works

1
Best-in-class encoder per format, not a generic canvas
Each output format routes to an encoder built for that format. JPEG goes through mozjpeg with trellis quantization for 10–20% smaller files than canvas.toDataURL at identical perceptual quality. PNG goes through oxipng with its zopfli-equivalent DEFLATE optimization. WebP uses libwebp with configurable method levels. BMP and GIF route through the native canvas encoder since those formats are rarely quality-critical.
2
Transparency handling surfaced, not hidden
When you convert a format with alpha (PNG, WebP, GIF) to one without (JPEG, BMP), the tool prompts for a background color rather than silently choosing white. This matters because a logo with a transparent background converted to JPEG with default white looks fine on a white page but wrong on a dark-mode layout. Preview in both modes before downloading.
3
Single-frame extraction for animation to static
Animated GIFs and WebP animations contain a sequence of frames. Converting to a static format (JPEG, PNG, BMP) extracts frame 0 — we expose a frame-picker to choose a different frame if the first is not the most representative. Going the other direction (static to animated) is not supported because a single frame is not an animation.

Honest limitations

· Animated GIF and animated WebP inputs have only the first frame preserved when converting to static formats; animation-to-animation conversion (GIF to animated WebP) is not supported here.
· TIFF, HEIC, AVIF, and RAW camera formats are not supported — browsers do not ship decoders for those. Convert to JPEG or PNG on your device first.
· Color space is assumed to be sRGB for all outputs; if your input carries a Display P3 or Adobe RGB profile and you need it preserved downstream, use a desktop tool like ImageMagick with explicit profile flags instead.

Pro tips

Never convert JPEG to PNG and expect a quality improvement

JPEG is lossy — once the encoder discarded high-frequency detail during the original save, that detail is gone forever. Converting the JPEG to PNG losslessly captures whatever pixel values are currently present, artifacts and all, in a larger file. The PNG is not higher quality than the JPEG; it is the same quality in a bigger container. The only legitimate JPEG-to-PNG conversion is when a downstream tool requires PNG specifically (asset pipelines, certain game engines, some print RIPs) — accept the file growth as a format-compliance cost, not a quality upgrade.

WebP is the right default for web delivery in 2026

Every major browser has shipped WebP support for years (Chrome since 2010, Firefox 65, Safari 14, Edge 18). It is typically 25–35% smaller than JPEG at matching quality, and 20–50% smaller than PNG for lossless use. The historical reasons to avoid WebP (Outlook email, some ad networks, Internet Explorer) are nearly irrelevant now. Convert your image library to WebP for web delivery and keep JPEG variants only for the specific downstream integrations that still reject WebP.

Flatten transparency deliberately, not by accident

The most common support ticket around format conversion is 'my logo turned white on a white background' — because a transparent PNG converted to JPEG flattened onto white by default and the logo was also white. Before converting any alpha-bearing format to JPEG, preview against both a white and a black background, pick a flatten color that contrasts with the subject (brand accent, neutral gray, or #FAFAFA rather than pure white), or keep the original format and just re-encode in place.

Frequently asked questions

Which format should I pick for the web?

WebP for nearly everything, with a JPEG fallback only if you are targeting clients that still do not support WebP (some email clients, legacy ad networks). WebP lossy handles photographs at about 25% smaller files than JPEG at matching quality, and WebP lossless handles screenshots and logos at about 25% smaller than PNG. If you can only serve one format and your audience includes Outlook email users or you have no HTML fallback mechanism, default to JPEG for photos and PNG for graphics. AVIF is smaller still but encoder support in browsers is limited and a pure JavaScript encoder would freeze the tab on medium inputs.

Will converting JPEG to PNG remove compression artifacts?

No. JPEG compression artifacts (the 8x8 block mosquito noise, the chroma bleed around saturated edges, the banding in gradients) are baked into the decoded pixel values. Converting that decoded buffer to PNG faithfully preserves every artifact at lossless precision. If the artifacts look ugly at display size, the fix is to re-export from the original RAW or layered source at higher JPEG quality, not to convert to PNG after the fact. PNG is appropriate when the input is already lossless (screenshot, export from Figma, rendered from SVG) or when a downstream tool demands PNG specifically.

What happens to transparency when I convert to JPEG?

JPEG has no alpha channel, so transparent pixels must be composited against a background before encoding. We let you pick the background color explicitly rather than defaulting silently — the default in most other tools is white, which surprises people whose logos become invisible on white-themed sites. For brand logos, pick a neutral color that reads correctly on your intended layout background, or better, keep the file as PNG or WebP which both support alpha natively. BMP also lacks alpha; same rule applies. Only PNG, WebP, and GIF carry transparency through a conversion round-trip.

Can I convert HEIC photos from my iPhone?

Not here, because browsers do not ship HEIC decoders for licensing reasons. On iOS you can either change the camera format under Settings > Camera > Formats > Most Compatible (which switches capture to JPEG), or you can convert existing HEIC files to JPEG via the Files app share sheet before uploading. On macOS, Preview opens HEIC and can export to JPEG or PNG via the File > Export menu. Once converted to a browser-supported format, our tool handles the rest of the pipeline — resize, compress, format-swap — without any further intermediate steps.

Is the conversion lossy or lossless?

Depends on the target format. Converting to PNG, WebP lossless, or BMP is lossless — the decoded pixel values are preserved exactly. Converting to JPEG, WebP lossy, or GIF is lossy: JPEG discards high-frequency detail via DCT quantization, WebP lossy does similar via VP8 intra-coding, and GIF quantizes to a 256-color palette via k-means clustering. For mission-critical archival work convert through lossless formats only; for web delivery the lossy formats are fine at quality 80+ and produce dramatically smaller files that load faster for users.

Format conversion is rarely the only transformation you need. After converting to the target format, image-compressor lets you tune quality and strip metadata for the final output; image-resizer handles the pixel dimensions if the conversion target has different display requirements than the source. When images need to end up as PDF pages for invoices or reports, images-to-pdf accepts any of the output formats from this tool. For screen captures and logo rasterization where you want to remove an existing background before converting, run background-remover first.
